An application study of the mixture of gibberellin, glucose and tin dichloride for determining inorganic phosphate in water(赤霉素-葡萄糖-二氯化锡混合液测定水中无机磷的应用研究)
引入赤霉素-葡萄糖-二氯化锡混合液作为钼蓝法的新显色剂.在1.0 mol/LHNO3介质和有机相中，赤霉素-葡萄糖-二氯化锡混合物与无机磷杂多酸反应生成杂多蓝，经萃取分离测定有机相，λmax = 690nm, 表观摩尔吸光系数为2.54 × 104L • mol-1 • cm-1. 浓度范围在0.1~4mg/L符合朗伯-比耳定律.赤霉素-葡萄糖-二氯化锡混合还原剂还原速度快，产物稳定性好，操作简便，结果令人满意....
