【摘要】 用亚氨基二乙酸型螯合离子交换树脂除去溴化钾中的重金属离子。结果表明.D751螯合树脂可以使浓度为500g/l的溴化钾溶液中铁、铅、铜、铋、钯、汞离子总含量降至0.5mg/l,为制得高感光度胶片提供了原料。更多还原

【Abstract】 Heavy metal ions in solution of potassium bromide have been removed by means of iminodiacetic acid chelating resin D751. The total content of Fe3+, Pb2+, Bi3+, Pd2+, Cu2+, Hg2+, etc in solution of KBr (500g/ l ) is less than 0.5mg/ l. The potassium bromide can be used as raw material for high photographic sensitive emulsion.更多还原
