摘要
试验了锑 与孔雀绿在盐酸介质中形成离子缔合物,并用苯萃取的最佳条件。在选定条件下,该离子缔合物的λmax=635nm,摩尔吸光系数ε=8 75×104,在10mL溶液中,锑质量在0～10μg范围内服从比尔定律。该方法已用于粗铟中锑含量的测定,结果满意。
The optimal conditions for spectrophotometric determination of antimony in crude indium with malachite green were inves tigated. In the medium of 2-3 mol/L HCl, Sb? with malachite green could form a stable green ion association complex which could be extracted by benzene.The maximun absorption wavelength was at 635nm with apparent molar absorptivity of 8.57×10~4 L·mol^(-1)·cm^(-1) in the selective condition.Beer's law was obeyed in the range of 0-10 μg of Sb? per 10 mL .This method has been applied to ...
