摘要
试验了多种类型的表面活性剂对硫氰酸钼络阴离子显色体系的光谱特性的影响。结果证明,混合表面活性剂对此体系的作用实际上只是非离子表面活性剂的作用。非离子表面活性剂能加速形成硫氰酸钼络阴离子的反应,降低反应的最适酸度。还通过萃取试验、紫外-可见光谱和红外光谱对非离子表面活性剂与此显包络阴离子形成的(钅羊)鎓型缔合物的增敏机理进行了探讨。
The effect of various surfactants on the spec-tral characters of molybenyl-sulfocyartate coloursystem was studied.It was proved that the effectof mixed surfactants on the system is essentiallythat of the nonionic surfactant concerned Wehave primarily proved that the mechanism of thesensitizing effect of the nonionic surfactant onthe system is through the formation of moly-benyl-sulfocyanate oxonium associated compoundwith the nonionic surfactant.
