1971年西末雄等人首次将巯基接到棉花的大分子链上,用以富集甲基汞。这种新型的巯基螯合固体吸着剂在环境监测,海洋调查,地质矿产,机械冶金,工业卫生,食品检验等应用广泛.已用于天然水,工业废水,海水,土壤,沉积物,岩石矿物,金属,生物,粮食,大气等各种样品中的钴、镍、锌、镉、铅、铊、铟、镓、钨、铜、银、锡、铋、锑、汞、砷、硒、金、碲、钯、铂等21种痕量元素的分离测定,实现了不同价态和形态间的有效分离。还应用于环境水质,大气现场采样富集及水、土、大气背景值调查.显示出富集倍数大,选择性强,吸附效率高等优点。
In 1971, Matsudo Nishio and others first connected the mercapto groups to the macromolecular chains of cotton for the enrichment of methylmercury. The new thiol chelate solid sorbents are widely used in environmental monitoring, marine investigation, geology and mineral resources, machinery and metallurgy, industrial hygiene, food inspection, etc. They have been used in natural water, industrial wastewater, seawater, soil, sediments, rock minerals Such as cobalt, nickel, zinc, cadmium, lead, thallium, indium, gallium, tungsten, copper, silver, tin, bismuth, antimony, mercury, arsenic, selenium, gold, Tellurium, palladium, platinum and other 21 kinds of trace elements separation and determination, to achieve a different valence and morphology of the effective separation. Also used in environmental water quality, atmospheric sampling and enrichment of the scene and the background value of water, soil and atmosphere survey shows that enrichment multiple, strong selectivity, high adsorption efficiency.
