Recent literature on biosorption as a sustainable environmental technology to remove pollutants

Abstract

Industrial advancement has been accompanied by increased pollution due to varioussynthetic chemicals that can contaminate water currents (Ullah et al. 2018). Some sourcesof pollutants include chemical by-products, such as herbicides, pesticides, pharmaceuticals, cosmeceuticals, pigments, and those derived from electroplating, mining, smelting, tex-tiles, leather, and metallurgical processes, among others (Bilal et al. 2018).The term wastewater is used to define those waters that come from the processesthat occur in the industry, which refers to any water that, at the time of manufacture or processing, comes into contact with raw materials, products, intermediates, by- products, or waste products, which are manually directed in different operations or unit processes (Gadipelly et al. 2014). Wastewaters can contain different pollutants, some of which will be detailed in the following.
