Determination of Lead Content in Pyrotechnics Used for Fireworks And
Advances in Engineering Research (AER), volume 130 5th International Conference on Frontiers of Manufacturing Science and Measuring Technology (FMSMT 2017) Determination of lead content in pyrotechnics used for fireworks and firecrackers based on inductively coupled plasma optical emission spectrometric approach (ICP-OES) 1, a Wu Jun-yi 1Technical Center for Dangerous Goods Testing of Guangxi Entry-Exit Inspection and Quarantine Bureau, Beihai, Guangxi, China [email protected] Keywords: fireworks and firecrackers; pyrotechnics; lead content; determination; inductively coupled plasma optical emission spectrometric approach; ICP-OES. Abstract. Inductively coupled plasma optical emission spectrometric approach(ICP-OES) is used to determine the lead content in pyrotechnics used for fireworks and firecrackers. Element of lead is commonly found as impurity in chemical materials used for pyrotechnics in fireworks and firecrackers. Statistical analysis shows that lead content in pyrotechnics is below 5%.Concept of this method: considering the weight of the sample is 400mg,constant volume is 0.5L and the concentration of lead is below 40mg/L in sample solution, the determination scope of the method for the lead content would be between 5%.Further experiments proved that the fitting correlation coefficient of lead calibration curve is 0.9997 or higher, recovery is 92.53%‒115.63%.The allowable differential value is 0.4% between two single tests under repeatable conditions. This method can completely satisfy the requirements of the fireworks and firecrackers industry with high accuracy and good precision. Introduction In China, fireworks and firecrackers are very important consumer recreational products in people’s everyday life since ancient times. Gorgeous colors produced by fireworks and firecrackers are even the leading role of foiling festal atmosphere in every grand holiday celebrations. -

Innovation in the Japanese Chemical Industry, Which Supports World Electronics Industry
View metadata, citation and similar papers at core.ac.uk brought to you by CORE Innovation in the Japanese Chemical Industry, Which Supports World Electronics Industry So Hirano I. Introduction This article focuses on innovation by outlining the history of medium- sized chemical companies in Japan and analyzes the factors that resulted in their success1). Industrialized countries always face attempts to keep pace with the economic challenges of emerging countries, which have recently entered the industrialization phase, irrespective of era or region. The development of technology standards in emerging countries allows them to enter product areas that were initially monopolized by industrialized countries. Such competitive situations result in industrialized countries losing their competitive advantage to emerging countries, which often have lower labor and production costs. In the1980s, Japan demonstrated enormous competitive strength on an international level in the electronics industry. However, in recent years, with the emergence and growth of companies based in Taiwan, China, and Korea, the market share of Japan’s electron- ics companies have fallen into a slump. Sony’s FY2012 ending deficit balance was recorded at its worst. Similarly, Panasonic and Sharp recorded large-scale deficits for the same fiscal year. Evidently, the future of Japan’s electronic industry is in jeopardy. 1) The content of this paper is largely based on Kikkawa and Hirano (2011). ――97 成城・経済研究 第204号 (2014年3月) To ensure that the decline of specific industries does not cause the overall decline of the economy, industrialized countries face the necessity of perpetually fostering new pivotal industries. However, the development of these industries is rather difficult. -

Alumni Newsletter
ALUMNI NEWSLETTER Department of CHEMISTRY and CHEMICAL ENGINEERING UNIVERSITY OF ILLINOIS at Urbana-Champaign NO. 3, JANUARY, 1970 An Extract of 1968-69 The annual report of the department is intended as much for our faculty as it is for the Dean and Vice-Chancellor who request it. It provides a fonnat for review and self-appraisal as plans are laid for the year ahead. Excerpts from the summary of the 1968-69 report may serve also to give you some feeling for the nature and breadth of our present concerns. Students and Instruction The number of Ph.D. degrees granted this year reached a high of 78, the highest since the post World War II flood of 84. Consolidation and experimentation continues in the general chemistry pro gram. The problems in Chemistry 100 are being worked out by Dr. Elizabeth Rogers. Televised and filmed lectures appeared in Chcmistty 101 and 102 as a result of an undergraduate instructional award to Dr. Gilbert P. Haight, Jr., director of the program. The undergraduate core laboratory, consisting of a series of three separate courses on "Structure and Synthesis," "Dynamics, Equilibrium, and Physical Methods," and "Chemical Fundamentals," went into full scale operation during the year under the guidance of Dr. T. L. Brown. The fall orientation program for new teaching assistants has been broadened and strengthened. Teaching loads of TA's were brought down to earlier levels. Facilities The major remodeling of the inorganic research laboratories in Noyes Labo ratory is nearing an end. A discouraging amount of badly needed remodeling of other old space in East Chemistty, Noyes Labo1·atory, and Chemistry Annex is in limbo due to lack of funds. -

This study was undertaken to evaluate the physical, proximate, phytochemical composition and the effect of coconut oil on lipid profile indices of albino rats. Materials and Methods:The proximate analysis was according to AOCS, phytochemical analysis was carried out with GC-FID.Thirty-five (35) albino rats were used for the lipid profile evaluation. Two phases of experiment with four (4) groups of male albino rats comprising of five (5) animals each, averagely weighing 180g-200g were employed. Phase 1 of the experiment was treated with coconut oil supplemented diet, where rodent chow was mixed with coconut oil while phase 2 experimental animals were treated with coconut oil by oral gavage. Group 1 served as the control for both phases while group 2, 3 and 4 were treated with 3ml/kg, 6ml/kg and 12ml/kg of coconut oil respectively for 4weeks. Results: The physical examination of the samples showed that the appearance of hot press method of extraction of coconut oil is pale-yellow while the oil from cold press method of extraction is colourless. -
