“…The production of activated carbon from sludge of different origins and their utilization for the removal of water pollutants has been also extensively studied [8][9][10]. The preparation of activated carbon is still an energy intensive process, thereby resulting in an expensive product.…”

The main purpose of this research was to assess sludge binding properties as a bioadsorbent towards cationic dyes. Digested sludge was used to adsorb a cationic dye (methylene blue) from aqueous solution. A complete spectroscopic analysis (FTIR, 1H NMR, and 13C NMR) was carried out on sludge before and after the adsorption of methylene blue and after two months of storage. Results showed the presence of important binding sites to cationic dyes. FTIR, 1H NMR, and 13C NMR analysis reflected the presence of carboxyl and amino groups, which play an important role in the adsorption of methylene blue due to chemical interactions. In addition, these techniques showed the accumulation of methylene blue after storage of samples for a two month period. The sludge matrix was modified by biological activity resulting in the preferential degradation of carbohydrate‐type materials. © 2016 American Institute of Chemical Engineers Environ Prog, 35: 1330–1337, 2016

“…Cd also harms human health through accumulation in food chains [4,5]. The common treatment methods for heavy metal ions in aqueous solutions include adsorption [6][7][8][9], bio-based methods [10][11][12], membrane separation techniques [13][14][15], electrolysis [16,17] and chemical precipitation [12,18]. Among these, micellar-enhanced ultrafiltration (MEUF), one of the membrane separation techniques, has received recent attention because it has the advantages of low energy consumption, easy operation, high permeation flux and high removal efficiency [1].…”

A mixture of the environmentally friendly biosurfactants rhamnolipids and sophorolipids was used as a source of micelles in this study. The Box-Behnken design and response surface methodology was used to investigate the influence of factors on micellar-enhanced ultrafiltration (MEUF). Simulated Cd-containing wastewater was used for testing. Based on single-factor experiments, the initial Cd2+ concentration, biosurfactant mixing ratio (α) and pH were chosen as influential variables, and both the Cd2+ rejection coefficient and permeation flux were used as responses. A predictive model based on a quadratic polynomial regression equation was established to determine the optimized enhanced ultrafiltration conditions for Cd. The results show that the regression equation is extremely significant and fits the data accurately. The optimal enhanced ultrafiltration conditions are as follows: initial Cd2+ concentration of 10.0 mg/L, α of 0.30 and pH of 9.58. Under these conditions, the rejection coefficient and the permeation flux of Cd2+ are 99.14% and 37.36 L/m2·h, respectively. The experimental results confirm that the experimental values agree well with the values predicted by the model. Further, these results provide theoretical support for using MEUF to treat heavy metal-containing wastewater when biosurfactants are used for micelle formation.

“…Among the natural products—animal, plant, and mineral‐based precursors have been studied extensively. Plant source biomass such as groundnut shell, rice husk, sugarcane bagasse, corn cob, coconut shell, wood, and bamboo have been used for the synthesis of ACs. These precursors mainly comprise of lignin and cellulose, both of which are polymeric forms of glucose molecule and the microstructures depend upon the relative concentration of these components .…”

This article presents the first report on systematic synthesis and evaluation of activated carbons from the cap and stalk of two diverse mushroom species namely, Ganoderma lucidum (GL) and Calocybe indica (CI) belonging to different classes white rot and brown rot respectively. A novel microwave induced H3PO4 activation followed by carbonization and KOH activation enabled the formation of activated carbon with hierarchical structures. The activated carbons from cap and the stalk of the mushrooms are different in terms of specific surface area, pore volume, and their electrochemical behavior. Specific surface area and pore volume from GL‐cap is as high as 2432.4 m2/g and 0.54 CC/g, respectively. After optimization, the activated carbons have high graphitic content, good thermal stability and show specific capacitance as high as 271.94 F/g, energy and power densities of 13.59 Wh/kg and 127.31 W/kg, respectively. All the carbons show good capacitance retention up to 10 000 cycles. The surface area and specific capacitance in the mushroom stalks are lower than the ones made from the caps and the highest surface area and specific capacitance are 1576.2 m2/g and 137.2 F/g respectively for GL‐stalk.
