【摘要】 在有柠檬酸的硝酸溶液中,微波作用下把溶矿和生成磷钼酸铵黄色沉淀一步完成;沉淀经过滤、洗涤后,溶于碱标准溶液中,然后用酸标准溶液滴定过量的碱,即可求出五氧化二磷的量,方法快速。更多还原

【Abstract】 In a mixed citric-nitric solution,the decomposition of phosphate rock and the creation of phosphate-ammonium molybdate(yellow deposit) are finished under the effects of microwave.Being filtrated and washed,the deposit is dissolved in standard alkali solution,and titrated by standard acid solution,by which P2O5 content in the phosphate rock is determined quickly.更多还原
