3. Micronutrients There Are 7 Essential Plant Nutrient Elements Defined As
3. Micronutrients There are 7 essential plant nutrient elements defined as micronutrients [boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), chlorine (Cl)]. They constitute in total less than 1% of the dry weight of most plants. The following discussion focuses primarily on the soil characteristics for the micronutrients. a. Boron (B) Boron is included in the Standard Soil Test. The level of soil boron is “insufficient” or “low” when extractable boron is less than 0.1 pound per acre. Soil boron is found in both organic and inorganic forms that are made available to plants as either or both soil organic matter is decomposed and/or boron-containing minerals dissolve. There may be between 20 to 200 pounds boron in the surface layer of South Carolina soils, but only a small portion is available to 3- plants. Boron, as the borate (BO3 ) anion, is mobile in the soil and can be easily leached from the surface soil. Calcium, potassium, and nitrogen concentrations in both the soil and plant can affect boron availability and plant function, the calcium:boron (Ca:B) ratio relationship being the most important. Therefore, soils high in calcium will require more boron than soils low in calcium. The chance for boron toxicity is greater on low calcium-content soils. The need to include boron in the fertilizer recommendation is determined by: • crop requirement • soil boron test level For any given crop when boron is recommended, a high rate of boron may be required on: • clay-type soils • soils that are high in water pH and/or calcium content • high organic matter content soils • soils where boron is broadcast versus boron being either banded or foliar applied Boron is routinely included in the fertilizer recommendation for the crops cotton, peanut, alfalfa, apple, root crops, cabbage, broccoli, and cauliflower, and when reseeding clover or where clover seeds are to be harvested. -

THE VAPOR PRESSURES OF MOLYBDENUM OXIDES AND TUNGSTEN OXIDES DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By PAUL EDWARD BLACKBURN, B. A. The Ohio State University 1954 Approved by* 1 ASMQMtfMlgMI The writer wishes to express his appreciation for the helpful guidance and criticism of Professor Herrick L. Johnston, under whose supervision this work was oarried out. He is also most appreciative to Dr, Michael Hoch for their many useful discussions and for his sugges tions . The author is very grateful to Mr. Janes Jones and Mr, L. £. Cox of the laboratory shop for their fine work on the apparatus used in this study. THE VAPOh PRESSURES OF MOLYBDENUM OXIDES AND TUNGSTEN OXIDES IflTBQPgCTIQM Although earlier investigations on the vapor pressures of molybdenum trioxide and tungsten tri- oxide have been reported in the literature (1,2) there is some doubt about the accuracy of the data. For this reason, and in order to extend the work to the other oxides, a study of the solid-vapor equili brium of the molybdenum-oxygen and tungsten-oxygen systems vas undertaken. The study was carried out by measuring the vapor pressures of the oxides using the Knudsen rate of effusion method. THEORY Sato of fiffmlga Hitfaad The Xnudaen (3) rate of effusion method consists of measuring the rate at which gas molecules escape through an orifice in the wall of a cell in which the gas la in equilibrium with a solid sr liquid. The equation for the pressure of a gas determined by the rate of effusion method is (4 ) p - » ^ * 5 “ , a ) where m is the rate of effusion in grams per square centimeter per second, R is the gas constant, T is the absolute temperature and M is the moleoular weight. -

First part of the process consists of ammonia gas neutralization of spent acid containing molybdenum, crystallization and filtration of ammonium molybdate, drying and roasting to produce a commercial grade molybdic-trioxide powder (molybdenum mass fraction 59.2 mas%). Second part of the process consists of grey cast alloying with MoO3 in inducing furnace. Final product was hardened iron alloy with high yield of molybdenum recovery (up to 86 %). Keywords: spent acid, ammonia neutralization, molybdenum-trioxide, alloying, cast iron. 1. INTRODUCTION Molybdenum compounds and his alloys could During the production of filament tungsten be used in a form of MoO3 and MoO2 as a catalyst wires for incandescent light bulbs a great amount in hydrocarbon reforming process [11,12], or as a of spent acid is obtained which contains by main electrocatalyst in fuel cell applications together with high concentration of sulphuric and nitric acid (500- Pt and Ru [13] or as silicides of molybdenum for 700 g/L of both acids) and also soluble high temperature structural purposes [14]. -

The DRDFs show a peak arising from Cs-I contact-ion-pairs at 390 pm for all the caesium iodide solutions. The hydration structure of the caesium and iodide ions has been revealed. Effects of the concentration and temperature on the formation of ion-pairs and on the hydration structure of the ions are discussed. 1. Introduction cept Li+ increases.
