Description

technical field

[0001] The invention belongs to the field of analysis and detection, and relates to a method for detecting the residues of p-aminoanisole and p-nitroanisole in soil. Background technique

[0002] With the overall improvement of our country's living standards and environmental protection awareness, people have put forward higher requirements for the living environment, shifting from the pursuit of comfort to safety and environmental protection. Therefore, whether the soil in close contact with humans is safe has become the focus of public attention. With urban expansion and urban planning, it has become a trend for chemical, printing and dyeing, pharmaceutical and other chemical companies to move out of the urban area. The old site of the industrial zone after the relocation will become a part of the future living area. The cumulative value of environmental pollutants in this area is a decisive factor. Whether it can be the key to living quarters, among which...
