在吸收光度法中,测定钼的显色试剂种类虽然很多,但实用的仍首推硫氰酸盐法。近年国内外对硫氰酸钼显色反应机理的研究并不鲜见,然意见不甚一致。至于在非离子型表面活性剂存在下测定钼,虽有人研究了TritonX-100-硫氰酸法,但有关平平加的应用则尚未见之报导,因此本文试图就在平平加存在下对钼的反应机理作一探讨。
In the absorption spectrophotometry, determination of molybdenum although a lot of color reagent, but practical is still the most important thiocyanate method. In recent years, the research on the color reaction mechanism of molybdenum thiocyanate at home and abroad is not uncommon, but the opinions are not consistent. As for the determination of molybdenum in the presence of non-ionic surfactants, although TritonX-100-thiocyanate method has been studied, there is no report on the application of equimolarity. Therefore, this paper attempts to investigate the effect of molybdenum A discussion of reaction mechanism.
