SELECTIVE PRECONCENTRATION OF ARSENITE ON MERCAPTO-MODIFIED SILICA-GEL HOWARD, AG; Volkan, Mürvet; Ataman, Osman Yavuz (1987-02-01) 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...
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...

Direct hydrothermal synthesis of palladium-incorporated silicate-structured mesoporous catalysts Sener, Canan; Doğu, Timur; Dogu, Guelsen (2007-01-01) Pd-Si-structured novel mesoporous nanocomposite catalytic materials, having quite high Pd/Si ratios, were synthesized by an acidic direct hydrothermal synthesis route. The nanocomposite catalytic materials were then characterized by XRD, XPS, EDS, nitrogen adsorption, and SEM techniques. Unlike MCM-41, the XRD patterns indicated a rather wide d((100)) band at a 2 theta value of about 1.9. The materials, with very high Pd/Si wt ratios between 1.43 and 2.66, were synthesized and had BJH surface area values be...
