Abstract

Water sources is contaminated with different types of impurities. Several technologies and materials are used for purification of contaminated water. Most of the reported technologies costly and produce secondary contaminants. Nowa day, researchers are used hydrogels for water purification. Hydrogels are applied drug delivery, catalysis, tissue engineering, sensing and removal of environmental pollutants, applications, and energy storage. Hydrogels have specific functional groups as –COOH, -SO₃H, -OH, CONH₂, -NH₂, -SH and other groups which are responsible for applications. Hydrogels were removes impurities from water through physio-adsorption, chemo-adsorption, sorption and secondary forces. The aim of this review is to explore the preparation method, conceptualization of hydrogels and their uses in water purification. It describes details of toxicants in water, different types of hydrogels and their synthesis methods. These hydrogels were used for water purification and evaluated for removal capacity with respect to toxicants in water. Nowadays hydrogels are modified based on their applications to create specific functionality on hydrogel. Specific hydrogel will be emerging tool for specific applications.

聚合物水凝胶在水净化中的作用：综述

水源受到各种杂质的污染。有几种技术和材料被用于净化受污染的水。大多数已报道的技术成本高昂，而且会产生二次污染。如今，研究人员使用水凝胶来净化水。水凝胶可用于药物输送、催化、组织工程、传感和清除环境污染物、应用和储能。水凝胶具有特定的官能团，如 -COOH、-SO3H、-OH、CONH2、-NH2、-SH 和其他负责应用的官能团。水凝胶可通过物理吸附、化学吸附、吸附和二次作用力去除水中的杂质。本综述旨在探讨水凝胶的制备方法、概念化及其在水净化中的应用。文章详细介绍了水中的有毒物质、不同类型的水凝胶及其合成方法。这些水凝胶被用于水净化，并对其去除水中有毒物质的能力进行了评估。如今，人们根据水凝胶的用途对其进行改性，使水凝胶具有特定的功能。特定的水凝胶将成为特定应用的新兴工具。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
