水中石油类测定方法及吸附剂活性的探讨

Determination Method of Petroleum in Water and Discussion on the Activity of Adsorbent

用红外分光光度法测定水中石油类,对测定原理、测定方法的检出限、硅酸镁吸附剂的特性、作用进行分析,讨论了硅酸镁活性和含水量的关系,以及降低活性后的硅酸镁对总萃取液中含极性分子动植物油的吸附性能。硅酸镁活性与含水量有关,可控制含水量使其对动植物油具有最佳吸附性能。

This paper mainly describes the infrared spectrophotometric in the determination of petroleum oil in the water.Based on the determination principle,the detection limit of the method,property and function of magnesium silicate adsorbent,the relationship between the activity of magnesium silicate and water content,and the adsorption performance of the activity-reduced magnesium silicate on the oil in extract liquid are discussed.The activity of magnesium silicate depends on the water content,so the best adsorption performance can be found out according to water content control.
