Summary:
Paraquat, also known as KeWutrace, is a widely used organic heterocyclic contact defoliant and herbicide, but it has strong toxicity to humans and animals, no specific antidote, and high mortality after poisoning. Effective measures must be taken in the early stage to prevent the absorption of poisons, prevent organ function damage, improve the treatment effect, and reduce mortality. The treatment of paraquat poisoning treated by early irrigation of bleaching soil in our department is summarized as follows. 1 pair

Summary:
The present invention discloses a production process of active bleaching soil. The process steps are:(1) Raw material pretreatment: using bentonite ore as raw material, repeatedly filtering sand and stones through a pulping tank and a disc mill to obtain bentonite raw material;(2) Inject bentonite raw material into a glass-lined reaction kettle, add concentrated sulfuric acid, prepare bentonite slurry and perform electric heating, all reactants are transferred to the neutralization tank, injected with cold water, cooled to below 20°C, added with an appropriate excess neutralizing agent, neutralized the excess sulfuric acid until the PH value is 7.5, and ammonium sulfate is generated. The production process proposed by the invention saves the drying workshop, saves a lot of coal resources, neutralizer washing method, saves water resources, and has no waste water.

Summary:
The present invention discloses a process for preparing active bleaching soil by attapulgite clay. The original soil is sorted or not sorted by dry method to ensure that the content of attapulgite is above 30%. After crushing, it is mixed with an appropriate amount of hot dilute acid solution, mixed into wet soil, and activated at room temperature. After drying, it is crushed into active bleaching soil. This process has rich sources of raw materials, saves energy consumption, simplifies the process, and the decolorization power of the product is above 110.
