Abstract

The invention discloses a propolis / polyvinyl alcohol heavy metal adsorbent. The propolis / polyvinyl alcohol heavy metal adsorbent is characterized by being prepared from the following raw materials in parts by weight: 2-4 parts of propolis, 3-5 parts of bone glue, 6-8 parts of polyvinyl alcohol, 1-2 parts of dodecyl polyglucoside, 0.3-0.5 part of succinic acid, 0.3-0.5 part of octenylsuccinate aluminum starch, 1-2 parts of sodium carboxymethyl starch, 0.1-0.2 part of sodium glutamate, 0.3-0.5 part of sodium alginate, 0.1-0.2 part of polysorbate-80, 6-8 parts of an auxiliary agent and 80-100 parts of water. The propolis / polyvinyl alcohol heavy metal adsorbent has the characteristics of strong heavy metal binding and adsorbing capacity and high adsorption capacity, has relatively good bactericidal and antibacterial effects, is safe, environment-friendly, non-toxic and harmless, does not cause secondary pollution to the environment in the wastewater treatment process, can effectively purify water, and is high in practicality.

Description

technical field [0001] The invention relates to the field of environmental treatment, in particular to a propolis / polyvinyl alcohol heavy metal adsorbent and a preparation method thereof. Background technique [0002] With the development of the global economy and society, environmental pollution is becoming more and more serious. Industrial wastewater, as the main source of environmental pollution, has been a major problem that has plagued countries all over the world for a long time. Heavy metal ions in industrial wastewater have strong carcinogenic, teratogenic, and mutagenic effects, which pose a serious threat to human health and the ecological environment. Therefore, it is very important to strictly control the pollution of heavy metal wastewater. [0003] Traditional heavy metal wastewater treatment methods mainly include chemical precipitation, ion exchange, membrane separation, etc. These methods usually have problems such as large investment, high energy consumptio...
