摘要

摘要:石墨烯相关二维(2D)材料在水处理中的使用,由于其独特的水运输特性、高表面积、优异的机械强度、无腐蚀性和可调的表面化学特性,在减少全球水资源短缺方面获得了极大的关注。氧化石墨烯(GO)作为一种很有前途的吸附剂,在水处理过程中也得到了广泛的报道,因为它对几种有害污染物具有更高的吸附能力。与传统吸附剂相比,氧化石墨烯可以提供几个优点;如两个基面可用于毒素吸附、规模化生产、含氧官能团和无催化剂条件。本文综述了氧化石墨烯的合成方法、化学性质、吸附性能及其在重金属去除中的应用。

Adsorptive Remediation of Heavy Atoms Contaminated Water Using Graphene Oxide: A Review
DOI: 10.2174/1874464812666181126103015 Abstract: The use of graphene-related two-dimensional (2D) materials in water treatment have gained tremendous attention in diminishing the worldwide water scarcity owing to their unique water transport properties, high surface area, excellent mechanical strength, non-corrosive features and tunable surface chemistry as discussed in patents. Graphene oxide (GO) has also received extensive coverage in water treatment processes as a promising adsorbent candidate because of its higher adsorption capacity for the removal of several hazardous contaminants. Compared to the conventional adsorbents, GO may offer several advantages; such as two basal planes available for toxin adsorption, scalable production, oxygen-containing functional groups and catalyst free conditions. The current review is focused on the synthesis methods, chemical, and adsorption properties of GO, and their applications for the removal of heavy metal species.
