摘　　要：根据水质石油类和动植物油的测定方法,结合实际工作经验,探讨了试剂硅酸镁吸附剂的特性、作用,讨论了硅酸镁活性和含水量的关系。通过灼烧去除有机杂质的硅酸镁需加6%(质量比)的蒸馏水进行纯化、降低活性。降低活性后的硅酸镁对总萃取液中含极性分子的动植物油具有最佳的吸附性能。According to the determination of.the water quality petroleum oil and animal and vegetable oils, and combined with practical work experience, Characteristics and function of Magnesium silicate adsorbent were discussed, and also the relationship between magnesium silicate＇s activity and its water content was researched. Add 6 % （mass ratio） distilled water to purifie the magnesium silicate which was removal of organic impurities by burning, and decreased the activity. After reduced the activity, the magnesium silicate has the best adsorption performance to the animal and vegetable oils in total extract solution.
