本文探讨了非离子表面活性剂(平平加)对孔雀石绿和硫氰酸钼之间显色反应的影响。研究结果表明,平平加犹如冠醚能与碱金属阳离子螯合,生成大阳离子进而与硫氰酸钼络阴离子缔合。这阐明了平平加的存在,它不仅与染料生成混合胶束,而且更重要的是与孔雀石绿竞争生成离子缔合物,这些影响导致孔雀石绿-硫氰酸钼的褪色。 This article explored the effect of nonionic surfactant (platingen) on the color reaction between malachite green and molybdenum thiocyanate. The results show that even if the crown plus ether can be chelated with alkali metal cation, generating large cation and then molybdenum thiocyanate anion association. This illustrates the existence of equator plus, which not only produces mixed micelles with the dye, but more importantly competes with malachite green to form ion-association compounds that result in the fading of malachite green-molybdenum thiocyanate.
