Abstract

The invention relates to a green synthetic Fe3O4-PdO nanocomposite material. A eucalyptus leaf extracted liquid is used as the reductant to reduce iron and palladium bimetallic ions simultaneously, and then calcination is carried out to obtain the Fe3O4-PdO nanocomposite material. The Fe3O4-PdO nanocomposite material prepared by the invention can be used as a material for arsenic pollution remediation in water.

Description

technical field [0001] The invention relates to a green synthetic Fe 3 o 4 -PdO nanocomposite material and its preparation method and application, belonging to the field of nanomaterial preparation. Background technique [0002] Arsenic (As) pollution is one of the major threats to global drinking water safety. The sources of arsenic pollution in the environment include natural effects (volcanic eruptions, weathering of rocks and minerals) and human activities (mining, smelting), among which human activities are the main source of arsenic pollution in the environment. Arsenic pollution in India, China, Vietnam and other places is very serious. Long-term exposure to arsenic-contaminated water can lead to skin cancer, lung cancer, kidney cancer, nervous system diseases, etc. Worldwide, different concentrations of arsenic pollution in the water environment have affected the health of more than 100 million people. The current common treatment technologies for arsenic-contai...
