摘要
本文详细探讨了乙醇、异丙醇、丙酮、吐温-80、OP对三氯偶氮胂光度法测定稀土元素La(Ⅲ) ̄[1]时选择性的影响。通过六个显色体系抗干扰能力的系统研究结果表明:通过加入乙醇、异丙醇、丙酮、吐温-80、OP中的某种,可使测定体系的抗干扰能力得到改善。
In this paper,the effects of alcohol,isopropanol,acetone,tuwen-80 or OP onselectivity of determination of La(Ⅲ)with IC-Ar senazo have been studied.The results of researchof six colour reaetions show that the selectivity of colour reactions can be improved by adding alco-hol,isopropanol,acetone,tuwen-80 or OP.
