近几年来,由于分子内不同组分间的协同作用而使多元络合物所具备的不同优异性能,早已引起人们的重视,利用多元络合物的显色反应测定痕量M_0的报导,也日有所见。碱性染料水相显色测定M_0迄今已有不少报导。对于碱性染料和杂多酸形成的多元络合物的显色反应灵敏度极高,在一定条件下,碱性染料的阳离子可以逐个取代杂多酸中氢离子而形成高配位数的离子缔合物,从
In recent years, due to the synergies between different components in the molecule, the diverse properties of the multi-complex have long been paid attention to. The detection of trace M_0 by the color reaction of the multivalent complex has also been reported. See you every day Alkaline dye aqueous colorimetric assay M_0 so far there have been many reports. For basic dyes and heteropoly acid complex formed by the complex reaction of the high sensitivity of the reaction, under certain conditions, the basic dye cationic heteropoly acid hydrogen ions can be replaced one by one to form a high coordination number of ions Compound
