铂皿浓缩法测定实验室用水中的硅含量,价格昂贵,成本较高,小型实验室很少会购买来监测实验室用水,且保存麻烦,不利于实验的开展。本法用聚四氟乙烯皿代替铂皿进行浓缩,降低实验成本,缩短实验时间,测定结果精度的和准确度均能达到测试要求。

Platinum crucible intended for determination silicon content in water suffers from several disadvantages that it is very costly,difficult to preserve and not widely accessible.In the paper,the method adopted Teflon pot to replace Platinum crucible in the process of evaporation and condensation can satisfy the requirements of accuracy and precision,meanwhile,the approach utilization Teflon pot is cost-effective and time-saving.
