Heavy metal ions absorbent prepared from pineapple leaves and preparation method thereof

Abstract

The invention discloses a heavy metal ions absorbent prepared from pineapple leaves. The heavy metal ions absorbent prepared from the pineapple leaves is characterized by being prepared from the following raw materials in parts by weight: 40 to 50 parts of pineapple leaves, 5 to 10 parts of attapulgite, 5 to 10 parts of zeolite powder, 3 to 5 parts of konjac powder, 1 to 2 parts of polyvinylpyrrolidone, 0.5 to 1 part of sodium alginate, 2 to 4 parts of calcium chloride, 1 to 2 parts of sodium phytate, 0.3 to 0.5 part of dodecyl polyglucosides, 4 to 6 parts of auxiliaries, and 40 to 60 parts of water. According to the heavy metal ions absorbent prepared from the pineapple leaves provided by the invention, the agricultural waste pineapple leaves are adopted as main raw materials to obtain a heavy metal ions absorbent, heavy metal is combined so as to be strong in adsorbability, the adsorption capacity is large, safety and environmental protection are realized, the absorbent is poisonless and harmless, secondary pollution cannot be caused to the environment during the wastewater treatment process, the raw material source is extensive, and the price is low, so that not only is the production cost effectively reduced, but also the aims of energy conservation and waste utilization are achieved, and higher economic benefit, social benefit and environment benefit are realized.

Description

technical field [0001] The invention relates to the field of environmental governance, in particular to a heavy metal adsorbent prepared from pineapple leaves 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 consu...
