摘要
对紫外(UV)光降解-过硫酸钾方法分析溶解有机磷的条件进行比较分析,在UV/加热条件下溶解有机磷的氧化率最高。进一步考察氧化剂的酸碱性和浓度对溶解有机磷氧化率的影响。Cl-和海水介质可以使溶解有机磷的氧化率显著降低。可以通过改变UV灯的功率、反应时间、反应温度、氧化剂等条件提高溶解有机磷的氧化率。
The experiment conditions to determination of total dissolved phosphorus by UV/ potassium persulfate are studied.It suggests that the oxidation efficiency of organic phosphorus is the highest under UV/heat among the four experiment conditions,i.e.UV,heat,UV/heat,and heat/UV conditions.Furthermore,the acidity and concentration of oxidant which influenced on the oxidation efficiency of organic phosphorus compounds are investigated.The oxidation efficiency of organic phosphorus decreases significantly when Cl-and seawater exists.And the oxidation efficiency can be improved by increasing the power of UV lamp,reaction time,reaction temperature,and oxidant,and so on.
