Drinking water arsenic-removal filter core and production method thereof

Abstract

The invention belongs to the technical fields of a novel material and a water purifier, and relates to a drinking water arsenic-removal filter core and a production method thereof. The arsenic-removal filter core is obtained by uniformly mixing arsenic adsorption powder, a porous particle arsenic adsorbent, an additive and a binder in proportion, and the materials are molded at proper temperature. A material formula design and a molding technology are used for preparing the arsenic-removal filter core, a nano arsenic-removal active substance is used for being fixed in the filter core, water permeability and current uniformity of the filter core are kept, so that the problems of inconvenient usage, increased cost due to easy loss of the nano arsenic-removal particle and secondary pollution can be solved. The arsenic-removal filter core has the advantages of loose and porous performance, good water permeability, and excellent intensity, the material and water are fully contacted, so that the product has excellent arsenic removal performance.

Description

technical field

[0001] The invention belongs to the technical field of new materials and water purifiers, and relates to an arsenic-removing filter element for drinking water and a preparation method thereof. Background technique

[0002] Arsenic is recognized as a carcinogen by many authoritative organizations such as the World Health Organization (WHO), the National Institute of Environmental Health Sciences (NIEHS) and the U.S. Environmental Protection Agency (US-EPA). Long-term contact with arsenic-contaminated water (including skin contact and drinking) can cause cardiovascular disease, nervous disorders, general fatigue, loss of appetite, nausea, and chronic poisoning symptoms such as skin lesions and keratinization, and may also cause skin cancer and liver cancer Cancer, lung cancer, kidney cancer, bladder cancer and other cancers also have a serious impact on children's intellectual development and physical development. When the human body ingests more than a certai...
