摘要
由于CI ̄-的影响,按LY2l6-79测定2l个试样的铁含量的结果,分别比按GB/T12496.8-90和原子吸收法平均偏高9.54%、6.78%。活性炭中铁主要以Fe(Ⅱ)形态存在,所占比例因活性炭品种不同而有所差异。
The content of iron in activated carbon was determined with ammoniurn thiocyanate (LY 216-79),phenanthroline(GB/T12496-90)and AAS.Results showed that:content of iron deterrnined with ammonium thiocyanate was 9. 54%and 6.78%higher than those with phenant1、roline and AAS respective-ly. The main form of iron in activated carbons was Fe(Ⅱ) and its content was different in various types ofactivated carbons.
