摘要
利用电导滴定法测定了粉煤灰中SO3 含量 ,并分析了影响测定结果的因素。结果表明 :电导滴定法的准确度与重量法接近 ,而且该法操作简单、迅速 ,每个样品仅需 35～ 40min。影响该法的主要因素是溶液的pH值和样品被溶解的温度及时间。
The content of SO 3 in fly ash was determined by conductometric titration and the factors influencing determination were analyzed.The results showed that the accuracy of conductometric titration is close to that of the gravimetry.It is easy and rapid in operation:it takes only 35～40minutes for one sample.The predominant factors influencing the accuracy are pH values of solution,dissolving temperature and duration for sample.
