摘要
在0.4mol/L硫酸介质中,在草酸及乳化剂OP存在下,锡与二溴羟基苯基荧光酮形成1:3配合物。可不经分离直接测定碳钢及低合金中0.010~0.08%锡。
In the presence of oxalic acid and nonionic surfactant OP and in H2S O4 medium (0.4mol/L), tin leacts with DBH-PF to form a 1:3 complex. Microamounts of tin in carbon steals and low-alloy steeis can be detaimined directly without sepaiation.
