Abstract

The invention discloses a preparation method for an adsorption material for polluted water heavy metals and a treatment method for polluted water heavy metals. The adsorption material for polluted water heavy metals is obtained by directly using maize straw as a raw material, and performing an xanthogenate modification treatment on the raw material by sodium hydroxide, epoxy chloropropane, carbon disulfide, magnesium sulphate and the like. The adsorption material prepared by the method disclosed by the invention is used for treating heavy-metal polluted water, and suitable for the conditions of neutral and acidic water environments; the adsorption material is low in dosage, high in removal rate, and capable of obtaining a good adsorption effect. The preparation method and the treatment method disclosed by the invention provide a new way for effective utilization for maize straw.

Description

technical field

[0001] The invention belongs to the field of phytochemistry and adsorption science, and in particular relates to a preparation method and a treatment method of an adsorption material for heavy metals in polluted water. Background technique

[0002] my country is a large agricultural country, and the amount of agricultural waste produced every year is huge, and corn stalks occupy a very prominent amount among many types of agricultural waste. However, in addition to some of the corn stalks being converted into ethanol, composted and returned to the field, or used as feed and edible fungus base material, or extracting xylitol, a considerable part of the corn stalks is directly burned, and due to Due to the uneven development of various regions, the proportion of burned corn stalks may be higher, which not only has an extremely low utilization rate and wastes resources, but also pollutes the environment and destroys the ecological balance. If the part of corn s...
