本文报导了铝-茜素S-三乙醇胺体系(pH=7.6)的吸附催化波,其峰电位为-0.78伏,波高与浓度在0.0005～0.025μg Al ml~(-1)之间呈线性关系。可应用于高纯二氧化硅中及天然水、地下水、铜选矿尾水中痕量铝的测定。
In this paper, the adsorption catalytic wave of aluminum-alizarin-S-triethanolamine system (pH = 7.6) was reported. The peak potential was -0.78 V and the wave height was linear with the concentration of 0.0005 ~ 0.025 μg Al ml -1 . It can be applied to the determination of trace aluminum in high purity silica and natural water, groundwater and copper dressing tailings.
