摘要
文章对十六烷基三甲基溴化铵、聚环氧乙烷、聚乙二醇（４００和６０００）、甲基纤维素和聚乙烯醇等６种凝聚剂在重量法测ＳｉＯ＿２过程中凝聚硅酸的效果进行了试验。这些操作较动物胶法方便、省时，测定标准样品结果与推荐值相符。
rocedures for gravimetric determination of silica have been developed with the application ofsix coagulation agents including cetyltrimethylammonium bromide,polyethylene oxide,polyethylene glycol(400),polyethylene glycol(6000),methyl cellulose and polyvinyl alcohol.As compared with the widely accepted gelatin method,any of the above techniques is simple andrapid,and the results obtained as tested with reference samples agree well with the recommendedvalues.
