微分电位溶出法具有灵敏度高,选择性好,成本低,操作简便等优点,可用于生物材料中铅、镉、铜、锌的测定[1,2,3,4],锰的测定报道很少,我们研究了锰在乙二铵底液中的溶出行为,发现在乙二铵底液中,锰有较好的溶出峰,可用于人发中锰的测定,方法简单、快速、样品用量少,效果满意。1
Differential potentiometric stripping method with high sensitivity, good selectivity, low cost, easy operation, etc., can be used for the determination of lead, cadmium, copper, zinc in biological materials [1,2,3,4], the determination of manganese is rarely reported , We studied the dissolution behavior of manganese in the ethylenediamine bottom solution and found that the manganese has a good dissolution peak in the bottom liquid of the ethylenediamine and can be used for the determination of the manganese in human hair. The method is simple, rapid and the amount of the sample Less, satisfactory results. 1
