无氨水替代方法研究

Research on Substitute of Non-ammonia Water

根据无氨水的特殊性,提出2种无氨水的替代方法:①实验室级超纯化水机二级水(电导率<1μS/cm);②新制一次蒸馏水(电导率≤7μS/cm)。通过实验证明这2种实验用水完全可作为无氨水使用,其性能和使用时限符合规范要求,其中超纯化水机二级水性能更优于标准方法制备的无氨水。

Two kinds of ways of substituting non - ammonia water are presented according to peculiarity of non - ammonia water, one of which is super purification water （conductivity is no more than 1 us/cm）, the other is one - off distilled water. The experiments show that the two kinds of water can be substitutes of non - ammonia water, both of which can reach related rules, and super purification water is better than standard non - ammonia water.
