摘要
研究了铅的碘络阴离子与孔雀绿形成三元络合物的显色反应条件,在磷酸介质中,三元铬合物被苯萃取,其最大吸收波长λmax=650nm,铅含量在0～30μg/l0ml,服从朗伯-比耳定律。采用以锶盐为载体分离、富集铅。试验结果令人满意。
The conditions were studied on color reaction of forming ternary complex from iodine and chromium anion in lead and malachite green.In phosphoric acid medium,ternary complex was extracted,the maximum absorption wave lengthλmax =650nm,the lead content were between 0～30μg /10ml,obeying Lambert -Beer' s Law.The result of lead separat-ing and concentrating was succesful taking strontium salt as the carrier.
