ICP-AES同时测定固体废物浸出液中钡、铍、镉、铬、铜、镍、铅和锌

摘要

Heavy metals such as barium, beryllium, cadmium, chromium, copper, nickel, lead and zinc in solid wastes were extracted with the acetic acid buffer solution, digested by HNO_3-HCI solution, and determined by ICP-AES. This method showed low detection limit of metals, good repetition,higher analysis efficiency and is applicable in determination of heavy metals in solid wastes.%采用醋酸缓冲溶液对固体废物样品进行浸提,经硝酸-盐酸消解后,ICP-AES测定消解液中的钡,铍,镉,铬,铜,镍,铅和锌.本方法具有检出限低、再现性好、分析效率高等优点,适用于固体废物浸出毒性的测定.
