Description

A mobile combined device for rapid determination of specific components in chemical fertilizers

technical field

The invention relates to the technical field of mobile combined devices, in particular to a mobile combined device for quickly measuring specific components in chemical fertilizers.

Background technique

In recent years, cadmium has been found to exceed the standard in rice on the market from time to time. Cadmium rice has become the focus of people's attention, and heavy metal pollution in soil has become a local "public nuisance". Fertilizer application is one of the main sources of heavy metals in soil. Long-term application of fertilizers with high content of heavy metals such as arsenic, cadmium, lead, chromium, and mercury can increase the content of heavy metals in the soil and cause the accumulation of heavy metals in the soil. At the same time, long-term excessive application may affect the quality of agricultural products. Heavy metals in fertilizers enter the food chain through farmland application and affect people's life and health. Therefore, their hazards should be paid attention to. For the health of people's lives, it is necessary to prevent heavy metals from flowing into the dining table from the source, that is, to reduce the heavy metal content in chemical fertilizers. Therefore, it is necessary to carry out heavy metal content testing before chemical fertilizers leave the factory.

The existing mobile combined device cannot grind the fertilizer to be tested, which will greatly affect the accuracy of the fertilizer measurement and the accuracy of the inspection results. At the same time, it cannot screen the fertilizer to be tested, which is prone to fertilizer congestion. For this reason, we propose a mobile combination device for rapid determination of specific components in fertilizers.
