Problems solved by technology

The methylene blue spectrophotometric method in the current national standard GB / T5750.4-2006 needs to adjust the pH value of the water sample and then add chloroform for multiple extractions, which makes the method cumbersome
Moreover, in recent years, water quality inspectors have improved the method in actual work, but most of them are improved on the addition of chloroform and the number of times of extraction, resulting in poor detection effect. Therefore, how to solve the above problems is an issue in this field. Content that technicians urgently need to study

Description

technical field [0001] The invention belongs to the technical field of anionic detergent testing, and relates to a detection device and method for measuring anionic synthetic detergents in drinking water. Background technique [0002] The extensive use of anionic synthetic detergents has caused water pollution, affecting the sensory perception of water and endangering human health. The determination of anionic synthetic detergent is an important detection index for various water quality monitoring. The methylene blue spectrophotometric method in the current national standard GB / T5750.4-2006 needs to adjust the pH value of the water sample and then add chloroform for multiple extractions, which makes the method cumbersome. Moreover, in recent years, water quality inspectors have improved the method in actual work, but most of them are improved on the addition of chloroform and the number of times of extraction, resulting in poor detection effect. Therefore, how to solve the ...
