“…In the sorption extraction of a metal ion, ion exchange processes are of great importance [3]. The developed porous structure and the presence of basic and acidic functional groups on the surface of sorbents are necessary conditions for the extraction of metal ions from industrial solutions.…”

“…The physical and mechanical properties and parameters of the porous structure of the carbon sorbent (C) and modified (MC) are given in table. Under static conditions at a temperature of 120 °C, studies were carried out on the adsorption of the copper (II) ion on the studied sorbents C and MC at optimal pH values (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) in equilibrium conditions in the concentration range 5-20 mg / L The contact time of the sorbent with salt solutions was 2 hours.…”

The data on accumulated mining waste in the territory of Kazakhstan are presented. Their processing has become very important in our time. The structure of surface-modified carbon materials with a grafted layer is given. New modified carbon sorbents were obtained, oleum was used as a modifying agent. It was revealed that the capacitive characteristics of the modified sorbent are significantly higher than that of the original one, which will make it possible to more efficiently extract the metal ion from wastewater and technogenic formations. Sorption is an effective method of extracting valuable components from wastewater and man-made formations. This method allows you to recover valuable substances with a high degree of wastewater treatment, which can be purified to the maximum permissible concentration of pollutants and then used in technological processes or in recycling water supply systems. Processing involves ores characterized by a low content of valuable components, fine dissemination and similar technological properties of minerals. The existing technologies for the development of minerals make it possible to use only a small part of the valuable mineral mass extracted from the subsoil, and the rest forms waste, which, as it accumulates and is stored, becomes one of the most significant factors of anthropogenic changes in the environment.

“…Producers have been invested in this segment to meet this need, but the industrial yield is not total and a lot of wastes and effluents are generated [1]. In current literature agro-industrial by-products are proposed as sustainable biosorbents alternative to activated carbon, one of the most applied adsorbents in the world [2][3][4][5][6][7][8]. However, the high production cost of activated carbon or chemical treatments, restrict the waste application as biosorbents and, in some cases, they are even unfeasible [9].…”

In this study, the wastes from cassava (CAW) and peach palm (PPW) agro-industries were investigated as potential low-cost biosorbents for removing the tartrazine yellow dye (TAR). The by-products were prepared by washing and drying steps and characterized into physicochemical parameters and microstructure. The effects of contact time, pH, dosage and dye concentration were analyzed for the biosorbents in comparison to commercial activated carbon (AC). The biosorbents were applied to the treatment of an effluent from a juice industry containing TAR. Cellulose was the main component of the biosorbents (31.47–51.20 g 100 g-1), which was correlated to the functional groups identified by ATR-FTIR spectra and the materials had a porous surface. The zero point of charge was 3.75 for PPW and 4.60 for CAW. The pH parameter had a significant effect on the adsorption process, with the maximum values of adsorption being reached at pH 2.0, with removal of 94.7% for PPW, 74.4% for CAW and 97.7% for AC, at the dosage of 7.5 g L-1 at 25.0 ºC. The adsorption of TAR was fast in the early stages, and at 120 min the three adsorbents reached the equilibrium. Isotherms of adsorption showed that Langmuir’s and Freundlich’s models fitted the best to the CAW and PPW experimental data, respectively. The wastes evaluated in this work can be an interesting alternative to TAR adsorption in the industrial effluent without being subjected to chemical treatments.

“…All conventional methods, such as adsorption method and electrochemical treatment, coagulation-flocculation, precipitation, liquid extraction, ion exchange, reverse osmosis, have been used at some point to remove or minimize heavy metal ion concentrations in industrial wastewater (Adamczuk & Kołodyńska, 2015, Pujol et al, 2013, Wu et al, 2016. In recent years, research has also started to investigate the use of various agricultural wastes as low-cost adsorbents to remove heavy metals from solutions (Johnson et al, 2008;Ramos et al, 2016;Sladjana et al, 2019, Tharanga Bandara et al, 2020, Hizkeal Tsade et al, 2020.…”

Mining waste dumps are present all over the world. One of the main problems of these solid deposits is the migration of heavy metals present in them due to the aqueous solutions flowing through them. The comparison of the removal of heavy metals from an aqueous solution of a real mining waste leachate under different conditions by two different agricultural wastes has been investigated. The effect of pH, contact time and dosage was studied using coffee grounds (CG) and walnut shells (WS), without pretreatment. The results obtained in the study showed the potential use of CG and WS for the removal of heavy metals, although the coffee grounds are the best adsorbents than the walnut shell.
