氨氮测定中几个问题的探讨

摘要

针对纳氏比色法测定氨氮过程中存在的问题,提出了相应的解决办法.消除了混浊和显色前后稀释问题,降低了空白吸光度,提高了测定的准确度.%An approach has been made that improve on the determination of amino nitrogen by Nashi colormetric method. The disturbance of turbidity and dilution problem color displaying are eliminated. It reduce the blank absorbility and improve the accurancy.
