| 摘 要： | 在文献的基础上，利用钼磷酸在浓硫酸作用下于乙醇介质中优先氧化萜烯酸及其衍生物，而本身被还原为钼兰的性质，本文建立了测定矿山废水中松脂油的方法，方法检出限为０．００６ｍｇ／５ｍｌ，回收率在８８％—１０７％之间，相对标准偏差为５．０５％。本文还对钼磷酸的溶剂选择，钼磷酸和浓硫酸的用量对吸光度的影响，以及浓盐酸的用量对萃取效率影响做了详细研究。

| Abstract: | Based on the literature,(1)by appliaction of the character of phosphato-molybdic acid that it may preferentially oxidate terpenol and derivants in alcohol:by the action of sulphric acid,and at the same time itself was reduced into molybdenum blue,this paper built an analysis method of determing rosin oil in mine waste water.The determination limit was 0.006mg/5ml,recoveries were between 88% and 107%,and R.S.D.Was 5.05%.In this paper selection of solvent for phosphato-molybdic acid,the effect of phosphato-molybdic acid and sulphic acid on absorption,and effect of hydrochleric acid on exeraction efficiency were studied carefully |
