摘要
通过研究样品制备时的酸度、时间等引起硅酸凝聚的条件以及光度测定条件的重新试验,确立了拜尔赤泥中二氧化硅的钼兰光度法测定条件。试验结果表明:方法相对标准偏差小于0.75%,加标回收率在98%～101%。
By studying the retest of the condition of silicic acid coagulation cau sed by acidity and time during sample preparation and the photometric determinat ion condition ,the determination condition of silica in Bayer red mud by molybde num blues photometry is dstablished in this paper.The test results prove that th e relative deviation of the method is less than 0.75%and the recovery rate of a dding standard solution is between 98%and 101%。
