摘要
在0.2mol/LH2SO4-10%乙醇介质中及紫外光照射条件下磷钼杂多酸光还原为磷钼蓝(λmax=780nm)。据此建立了一个测定0.05~2.0μg/mL磷的光化学分析新方法,并用于试样分析。探讨了光化学反应机理。
Under the conditions of 0 2mol/L sulphuric acid -10% ethanol medium and irradiation of UV-light, molybdophosphate heteropoly acid is reduced to its heteropoly blue (λ max =780nm) On those grounds,a new photochemical spectrophotometric method for 0 05~2 0μg/mL phosphorous has described, and applied to determining phosphorous in real samples The photochemical mechanism is also discussed
