【摘要】 采用含硫醇基的螯合剂转化聚苯乙烯基离子交换纤维，开发出一种制备螯合物纤维的简单方法．实验表明，双硫腙（ＤｚＳ）很容易而且牢固地被聚苯乙烯基阴离子交换纤维固定．载ＤｚＳ的聚苯乙烯基螯合物纤维可用于重金属离子的选择性收集．将吸附了重金属离子的纤维，不经洗脱直接进行原子吸收光谱测定，可测定出纤维上含有的金属离子．更多还原

【Abstract】 The polystyrene based ion exchange fiber is converted by chelating agent containning thiol, which develops a simple method that can make chelating fiber. Dithizone (DzS) and other sulfonated bodies can be easily fixed by polystyrene based anion exchange fiber. Polystyrene based ion exchange fiber is of great use in selective collection of heavy metal ions. The fibers which have absorbed heavy metal ions are measured by atomic absorption spectra so as to measure metal ions on the fiber.更多还原
