【摘要】 本文研究了钼（Ⅳ）在 HCl—KCl 缓冲液介质中催化过氧化氢氧化对氨基乙酰苯胺和β—萘酚的显色反应。并拟定了催化分光光度测定土壤中痕量钼的新方法,本方法的灵敏度为8×10^-10g/ml,测定范围0～1.0μg/25ml,本法已用于土壤中痕量钼的测定。更多还原

【Abstract】 In this paper,the Mo（Ⅵ）catalytic effect on the colour reaction,inwhich the mixture reductant of β-naphthylaminc and P-Aminoa clortanilide isoxidized by H₂O₂ in a buffer solution HCl-KCl,has been examined in detail.Optimum condition for determining Mo（Ⅵ）had been established.The sen-sitivity of this method was presented as 8×10^-10g/ml,The range of determ-ination was 0～1.0μg/25ml.This method has been used in determining the tr-ace amounts of Mo（Ⅵ）in soil.更多还原
