This triply Born-Oppenheimer system is a nonmolecular, three-dimensional, metallic alloy, despite a prominent layered structure. A significant number of enthalpically near-degenerate structures, with exceedingly small energy barriers for distortions, and characteristic instabilities in the phonon spectra suggest that even at very high pressures PbH4 may exhibit both metallic and liquidlike properties and sublattice or even full melting.

  • Determination of Lead in Complex Sample Matrices by Atomic Fluorescence Spectrometry: Optimisation of Online Hydride Generation Blanca G
    https://cimav.repositorioinstitucional.mx/ Determination of lead in complex sample matrices by atomic fluorescence spectrometry: optimisation of online hydride generation Blanca G. Beltrán, Luz O. Leal, Laura Ferrer & Victor Cerdà Lead hydride or plumbane (PbH4) generation was optimised by exploiting a simple flow-injection method coupled to atomic fluorescence spectrometry (HG-AFS), and allowing ultra-trace lead determination. Plumbane was generated through two methods: (1) 5% (v/v) H2O2 was employed as oxidant with 1.5% (m/v) KBH4 as a reducing agent and 1.5% (v/v) HCl solution; (2) with 1.5% (m/v) K3[Fe(CN)6] as an oxidant/ sensitiser, 1% (m/v) KBH4 as a reducing agent and 1.5% (v/v) HCl. Variables such as reagent concentrations, flow rates and sample and reagent volumes were tested and critically compared. The best results were obtained with potassium ferricyanide K3[Fe(CN)6], achieving a detection limit of 0.03 μg Pb L−1 and a relative standard deviation (RSD) of 1.1%. The selected method was validated by analysis of certified reference materials such as SRM-2976 (mussel tissue) and BCR-610 (groundwater), with good agreement with the certified values. The developed methodology was successfully applied to different environmental sample matrices, such as rain water, tap water, ground water, spring water and drinking water, and biological samples, i.e., human blood, plasma and serum. Keywords: lead hydride; oxidising agents; atomic fluorescence; water samples; blood analysis 1. Introduction In recent years, interest in the determination of lead has been increased, particularly in biological, food and environmental sample matrices [1–4].

  • Chemical Inventory Packet / Calarp Lists / HFD / Dmg 2004 Table 1
    HAYWARD FIRE DEPARTMENT CHEMICAL INVENTORY WORKSHEET To prepare a chemical inventory based on the Hayward Fire Code, you are required to report the quantities of chemicals found in the facility, separated by Hazard Category, and by location. You are also to classify the chemicals as to storage and manner of use. Handling and storage requirements are determined by these factors: the nature of the chemical or its hazard; the location; the manner of use or storage; and the quantity involved in each particular manner of use or storage. A Control Area is a building, a portion of the building, or an outside area where chemicals are allowed to be stored, dispensed, used or handled subject to certain conditions and requirements. This packet consists of the following lists and the Chemical Inventory Worksheet form: 1. Hazardous Materials Hazard Categories. This is the list printed on goldenrod paper. Based on the Uniform Fire Code, this is the classification of chemicals by hazard categories. The different hazard categories are defined and examples are provided for each. Most chemicals exhibit more than one hazard, and all hazards should be considered when preparing your chemical inventory. 2. Tables of Regulated Substances Under the CalARP Program. Printed on pink paper, these are the lists of flammable and toxic substances that, if present at or above certain threshold quantities, will require the preparation of a Risk Management Plan 3. Federal List of Extremely Hazardous Substances (EHS). This list is printed on blue paper. These are the substances that the federal government classifies as extremely hazardous substances. The Hayward Fire Department has included “CalARP-Listed or EHS-Listed Chemicals” as a separate Hazard Category.

  • Studies of the Hydrides of the Heavier Group 14 Elements
    Studies of the Hydrides of the Heavier Group 14 Elements Daniel Hugh Brown A thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy to the University of Edinburgh 1998 Declaration This thesis has been composed by myself and it has not been submitted in any previous application for a degree. The work reported within was executed by myself, unless otherwise stated. May 1998 1 Abstract The chemistry of some simple tin hydrides (CH3)4_ SnH (x = 1-4) has been investigated with particular reference to their reactivity towards the reagents NaH, KH, alkyl lithium compounds, and the ylids Me 3P C H2 and Ph3PCH2 . It has been found that the reaction between the stannanes and alkali metal hydrides or the ylids produces salts containing the respective stannyl anions, [Sn(CHa)sH] (x = 0-3). These salts have been characterised by low tem- perature infrared spectroscopy, the results of which are in good agreement with the results of ab initio calculations. In contrast, reactions involving alkyl lithium compounds proceed by transmetallation with elimination of LiH and alkylation of the tin centre. The technique of in situ crystal growth at low temperatures has been used to obtain X-ray crystal structures of Me 3P C H2 , Me2Sn H2 and Me3Sn H. The structure of the ylid in the solid phase has been shown to resemble the calculated structure of a transition state involving rotation of the CH 2 group about the P-C aids. The reaction between monochlorostannane and sodium metal produced small quantities of Sn 2H6, detected by mass spectrometry.
