海水监测中总氮小于三氮的原因分析及改进建议
Cause Analysis and Improvement Suggestion for Total Nitrogen Less than Three Nitrogen Compounds in Seawater Monitoring
摘要
Abstract
The reason that the measured total nitrogen is less than the sum of ammonia nitrogen,nitrite nitrogen and nitrate nitrogen(hereinafter referred to as"three nitrogen compounds")is found by analyzing and comparing the whole process of seawater sampling and monitoring.In this paper,suggestions are proposed for improvement according to the common non-conformance items in sample collection,sample retention,reagent preparation,and selection of monitoring methods.The monitoring of total nitrogen and nitrogen compounds in seawater is significantly affected by salinity,and the reason why total nitrogen is less than the sum of three nitrogen compounds is complex and diverse.It is necessary to put forward pertinent suggestions and take effective measures to improve the reaction mechanism.关键词
