Selective Preconcentration of Gold from Ore Samples
Refiker, Hurmus; Merdivan, Melek; Aygun, Ruveyde Sezer (Hindawi Limited, 2018-9-12)
A simple and selective method has been developed for preconcentration of gold in ore samples. The method is based on use of N, N-diethyl-N’-benzoylthiourea (DEBT) as selective chelating agent and Amberlite XAD-16 as solid sorbent. Sorption behavior of gold with DEBT impregnated resin under optimized conditions has been studied in batch process. The gold ion capacity of the impregnated resin is calculated as 33.48 mg g<jats:sup>−1</jats:sup> resin (0.17 mmol g<jats:sup>−1</jats:sup> resin). The selective pre...

A surface-modified silica gel has been developed for the pre-concentration of arsenite from natural waters. The reaction of silica gel with (3-mercaptopropyl)trimethoxysilane produces a mercapto-modified silica gel with a silver capacity of ca. 0.9 mmol g–1. This material selectively removes arsenite from samples that also contain arsenate, monomethylarsonate and dimethylarsinate, and can be employed for both the column and batch pre-concentration of arsenite. Under column and batch conditions recoveries of...
