“…Summarizing, dyes can be removed, degraded and detoxified by enzymatic biological process and also physical adsorption by using SMS [163]. SMS in bioremediation of dye is definitely more time saving and cost effective [7].…”

Nowadays, the food sector is highly concerned with environmental issues and foreseen to develop strategies to reduce waste and losses resulting from activities developed in the food system. An approach is to increment added value to the agro-industrial wastes, which might provide economic growth and environmental protection, contributing to a circular economy. Mushroom by-products represent a disposal problem, but they are also promising sources of important compounds, which may be used due to their functional and nutritional properties. Research has been developed in different fields to obtain value added solutions for the by-products generated during mushroom production and processing. Bioactive compounds have been obtained and applied in the development of nutraceutical and pharmaceutical formulations. Additionally, other applications have been explored and include animal feed, fertilizer, bioremediation, energy production, bio-based materials, cosmetics and cosmeceuticals. The main purpose of this review is to highlight the relevant composition of mushroom by-products and discuss their potential as a source of functional compounds and other applications. Future research needs to explore pilot and industrial scale extraction methods to understand the technological feasibility and the economic sustainability of the bioactive compounds extraction and valorization towards different applications.

“…10 Conventional physicchemical processes for dye removal from wastewater include oxidation, photochemical degradation, reverse osmosis, membrane separation, coagulation and adsorption. [11][12][13][14] The latter is one of the most effective methods that has been successfully adopted for the removal of wastewater color. 15 The activated carbon is a largely used adsorbent seeing that it has a high adsorption capacity of organic materials.…”

Montmorillonite-Fe3+ (MMT-Fe3+) nanoclay mineral was successfully prepared using a ferric chloride precursor. The prepared sample was characterized using IR, XRD, BET and SEM-EDX. We have explored the highly efficient and environmentally benign MMT-Fe3+ for adsorption of Crystal Violet (CV) dye from aqueous solution under ambient conditions. The MMT-Fe3+ was interacted with CV dye solution at different pH, temperature and solid-to-liquid ratio. The concentration of CV dye removal was estimated from its optical density at λmax = 590 nm using UV–Vis spectrophotometer. The CV dye removal was rapid at basic pH and increases with temperature up to 40 °C. A complete reduction (100%) was occurred in about 7 min at pH 7 and 10 while at pH 3 in about 10 min. The time taken for complete reduction at 0, 30 and 40 °C are 10, 7 and 5 min respectively. The removal followed by adsorption of dye molecules on the spent nanoclay mineral was evident from SEM/EDX analysis. More importantly, MMT-Fe3+ could be separated and retrieved easily after the reaction by centrifugation from the degraded CV dye solution. The experimental results of CV dye removal from MMT-Fe3+ follows the pseudo first order kinetics. This study reveals that MMT-Fe3+ has the potential to be used as reductant/adsorbant to remove cationic pollutants effectively and rapidly from drinking water and large scale of industrial wastewater.

Abstract:In this work, surface-functionalization agents and various salts as auxiliaries were used to improve the adsorption capacity of biochars produced via hydrothermal carbonization of glucose, cellulose, and hazelnut shell. The effect of surface functionalization with different acids and bases as well as neutral salts on the adsorption of methylene blue and methyl orange was investigated using Boehm titration, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy techniques. Surface functionalization of biochars leads to an increase in the number of oxygen-containing functional groups on the surface, thus increasing the adsorption capacity. To probe the influence of ionic strength on the adsorption process, three auxiliaries, namely potassium chloride, cetyltrimethylammonium bromide, and sodium bicarbonate, were examined. The increase in total electrolyte concentration significantly affected the pH of the solution and as a result electrostatic interactions between dyes and biochars. Dye adsorption capacities reached 234.57 mg/g for methylene blue and 306.13 mg/g for methyl orange in the presence of cellulose-based and NaOH-functionalized biochar and glucose-based H 2 SO 4 -functionalized biochar, respectively.
