“…This system attracts pollutants from polluted aqueous media to be accumulated on the active sites of sorbent surface [5]. Particular pollutants and sorbent properties including surface or pore diffusion, electrostatic interaction, hydrogen bonding, and van der walls forces as well as chosen operating conditions are some dominant factors affecting adsorption process [33,34]. Several activation techniques such as carbonization, chemical activation, and pyrolysis can also be conducted to increase the adsorption capacity of the sorbent prior to adsorption process (Figure 1) [35][36][37].…”

In this review article, the recent development of organic sorbents derived from plant and animal waste for treating polluted aqueous media is presented. The application of biomass has been recognized reliable to adsorb hazardous pollutants contained in wastewater generated by emerging industries. This paper also discusses other existing technologies for removing pollutants including heavy metals, dyes, oil and grease, antibiotic and phenolic compounds from polluted aqueous media. Furthermore, several prominent examples of plant and animal wastes such as eucalyptus bark, pine bark, rice husk, various fruit peels, and animal bones are also properly reviewed. The effects of modification techniques on sorbent performance such as carbonization, pyrolysis, and chemical impregnation using acid or alkaline chemicals are considerably included. Some gaps in current literature are also discussed including the tendency of certain targeted pollutants, the use of simulated aqueous media, the scale of research projects, and the prominent modification procedures. Eventually, based on the relevant literature, clear conclusion has been drawn that these natural disposals have great potentiality as environmentally friendly sorbent alternative to other commercial expensive sorbents, and their reuse has been part of green solutions supporting a circular economy system.

“…Based on the origin of the material, dyes are classified as natural (natural sources such as plants, animals, including hematoxylin, carmine and orcein) and synthetic (organic, inorganic compounds) [6]. Based on the charge of the particles, they are divided into ionic (cationic and anionic dyes) and non-ionic.…”

“…Ionic dyes generally pose a higher risk, which is due to their reactivity and carcinogenic nature [5,7]. According to their colour and the functional group attached to the chemical structure, there exist chromophore dyes (azo, anthraquinone, indigo, xanthenes, phthalocyanine, nitrated, and nitrosated and triphenylmethane dyes) or auxochrome dyes (they contain acid or anionic dyes, basic or cationic dyes, vat dyes, direct dyes, mordant dyes, reactive dyes, azo dyes, and dispersed dyes) [3,6,8].…”

Synthetic dyes widely used in many kinds of industry affect the colour of wastewater when released to environment due to insufficient treatment in typical sewage treatment plants. Only a small dose of those dyes may significantly affect colour of water and, according to the chemical composition, may pose risks to wildlife and humans. In the research described in this study, decolorization of three various dyes was investigated. Since colour removal of Congo Red such as Methylene blue using ozone have been reported by several authors, and the literature on Naphthol Green B is rather limited, in the present study we compare the decolorization rate of CR, MB and NGB. The colour removal occurred quickly and more than 90% of colour reduction was achieved within 3-6 minutes throughout all tested pH of the solution.

“…Synthetic dyes are gradually replacing natural dyes, especially in textile industries. In addition to the above categorization, dyes are very often classified according to chemical structure, including azo, anthraquinone, indigoid, nitroso, nitro and triarylmethane [7,8]. Azo dyes are the most important group of synthetic dyes and represent the largest class of the dyes used.…”

Over the last few decades, nanotechnologies have gained a great deal of attention, and various nanomaterials and techniques have been developed for water remediation. This study deals with the adsorption of Naphthol green B onto the magnetite nanoparticles synthetized by the coprecipitation method at the laboratory temperature. According to the obtained results, the sorption process is obvious only at the acidic condition when the pH of solution decreases to pH level 3. According to nonlinear fit of experimental data, the sorption of the Naphthol green B onto magnetite nanoparticles is assumed as multilayer, while the Freundlich model fits better (96.158 %) than the Langmuir model does (55.941 %).
