摘要
在硫酸介质中,罗丹明B与磷锑钼杂多酸生成缔合物,最大吸收峰位于590nm,表观摩尔吸光系数为8.5×104L·mol-1·cm-1,在0-5μgP/50mL范围内遵守比尔定律,组成摩尔比为,P:Sb:Mo:R=1:2:11:2。
A new sensitive colour reaction of rhodamine B-phosphoantimomoly bdate heteropoly acid system in a H2SO4 solution has been developed. The ion-association complex exhibits maximum absorption at 590nm With an apparent molar absorptivity of 0-5 μg/50mLfor P(V). The molar ratio of the components of P:Sb:Mo:R=1: 2: 11: 2.
