“…Maximum adsorption capacity for fluoride was 2.3 mg/g for the mixed matrix membrane at room temperature. Zhang et al (1999) satisfactorily removed Cd 2+ and Sr 2+ ions via adsorption on cellulose/alginic acid (RC-AlC) ion-exchange membrane. Vinodhini and Sudha (2016) fabricated a novel ultrafiltration membrane prepared by phase inversion method using cellulose acetate, nano chitosan, and polyethylene glycol.…”

Application of polymeric membranes for the adsorption of hazardous pollutants may lead to the development of next-generation reusable and portable water purification appliances. Membranes for membrane adsorption (MA) have the dual function of membrane filtration and adsorption to be very effective to remove trace amounts of pollutants such as cationic heavy metals, anionic phosphates and nitrates. In this review article, recent progresses in the development of MA membranes are surveyed. In addition, recent progresses in the development of advanced adsorbents such as nanoparticles are summarized, since they are potentially useful as fillers in the host membrane to enhance its performance. The future directions of R&D in this field are also shown in the conclusion section.

“…Therefore, it is needed to reduce the amount of this ion particularly in wastewater streams of hydrometallurgical and other industries. Filtration, adsorption, reverse osmosis, solvent extraction, electro-kinetic and membrane separation techniques are used for removal of heavy metals from aqueous solutions [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Among them adsorption has been shown to be an economically feasible alternative method for removing heavy metals from wastewater and water supplies [11][12][13][14][15][16][17][18].…”

“…Heavy metals can also be removed by a variety of biosorbents (Diels et al 1995;Kapoor and Viraraghavan 1998;Zhang et al 1999;Bankar et al 2009). In particular, environment-friendly agro wastes have emerged as important adsorbents (Bailey et al 1999;Pino et al 2006;Farinella et al 2007;Mahvi et al 2008;Al-Masri et al 2009).…”

Paper mulberry (Broussonetia papyrifera) leaf powder was used to remove heavy metal ions from aqueous solutions. The specific uptakes of Cu (II), Pb (II), and Cd (II) by the leaf powder were 43.40±0.2, 43.9±0.5, and 30.65±0.9 mg g −1 , respectively, when 500 mg L −1 of the metal solutions were used. The data fitted well to the Langmuir isotherm. The process followed the pseudo-second-order kinetic equation and intraparticle diffusion played an important role in the adsorption process. On the basis of the calculated thermodynamic parameters such as standard enthalpy (ΔH°), entropy (ΔS°) and free energy change (ΔG°), it was inferred that the sorption process was endothermic and spontaneous in nature. The surface properties of the leaf powder (revealed by scanning electron microscopic observations) were suitable for the metal adsorption process. Energy dispersive X-ray fluorescence analysis confirmed the sequestration of the metal ions by the leaf powder. Fourier transform infrared spectroscopy implicated that different functional groups on the leaf powder were involved in the metal adsorption process. The results obtained from this study implicated that the B. papyrifera leaf powder was a good choice as a metal adsorbent. This abundantly available natural and ecofriendly biosorbent could be effectively used to develop a technology in the future.
