| 摘 要： | 本文研完了利用二苯卡巴肼分光光度法间接测定水泥的SO_3。该方法基于被测SO_4~(2-)与BaCrO_4发生沉淀转化反应,用二苯卡巴肼分光光度法测定游离出的CrO_4~(2-),从而计算出SO_3的百分含量。本方法应用于水泥样品中SO_4的测定,结果满意。

| Abstract: | A method for the indirect spectrophotometry determination of SO_3 in cement has been studied. The method is based on SO_4~(2-) which is reacted with an excess of BaCrO_4 and the free chromate is then determined by spectrophotometry using diphenylcarbazide at 540nm. This method has been applied to the determination of SO_3 in cement with satisfactory results. |
