Alkaline decomposition of synthetic jarosite with arsenic
The widespread use of jarosite-type compounds to eliminate impurities in the hydrometallurgical industry is due to their capability to incorporate several elements into their structures. Some of these elements are of environmental importance (Pb(2+), Cr(6+), As(5+), Cd(2+), Hg(2+)). For the present paper, AsO4 (3-) was incorporated into the lattice of synthetic jarosite in order to carry out a ...
متن کاملThe Behavior of Arsenic during the Thermal and Chemical Decomposition of the Ammonium–Arsenic Jarosite
Arsenic, an element of environmental impact, can be incorporated into jarosite–type compounds and remain stabilised within the structure under a wide range of environmental conditions. In this study, a sample of ammonium–arsenic jarosite was synthesised by precipitation in sulphate medium at controlled pH of 1.2–1.8. The behaviour of arsenic during the thermal and chemical decomposition of jaro...

متن کاملIsolation and Structural Characterization of Alkali and Alkaline Earth Metal Salts with Synthetic Non Cyclic Ionophores
In the present study, an investigation on the complex formation between mono- and divalent metal ions (Na+, K+, Li+ and Mg2+) in the form of salt with different podands using various solvents has been carried out. Isolated complexes were characterized by different spectroscopic techniques viz. IR, NMR and elemental analysis. On the basis of ...
متن کاملThe Alkaline Decomposition of Serine
A method for the quantitative estimation of arginine is included by Van Slyke (1911-12) in his procedure for the determination of the nitrogen distribution numbers of proteins. The amino acids present in the protein hydrolysate are divided into two groups by means of phosphotungstic acid. The portion precipitated by t,his reagent is referred to as the basic or diamino fraction and the portion n...
