“…The statistical analysis proved that FMWCNTs had better adsorption capacity compared to magnetic biochar. Li et al (2010) reported that copper removal efficiency of CNTs/CAl (carbon nanotube/calcium alginate composites) was high and reaches 69.9% even at a lower pH of 2.1. The copper adsorption capacity of CNTs/CA can attain 67.9 mg/g at copper equilibrium concentration of 5 mg/L.…”

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.

Nanomaterials exhibit unique physical and chemical properties and, hence, they have received much attention from scientists and researchers in different areas of environmental sciences, specifically in bioremediation. Bioremediation provides a good clean-up strategy for some types of waste, but as it is expected, it will not be useful for all. For example, bioremediation may not provide a feasible strategy at sites with high concentrations of chemicals that are toxic to most microorganisms. These include heavy metals and salt. Further, the advancement in science and technology has increased standard of living which directly or indirectly contributes to the increase in waste and toxic material. Therefore, the remediation of contaminants by use of existing technology is not effective and efficient in cleaning up the environment. Hence, nanomaterials may be applied for bioremediation, which will not only have less toxic effect on microorganisms, but will also improve the microbial activity of the specific waste and toxic material which will reduce the overall time consumption as well as reduce the overall cost. In this paper we have briefly summarized the major types of nanomaterials that have been used so far in bioremediation of waste and toxic materials.

The present study was conducted to evaluate the possibility of using peanut hulls for the removal of Fe +3 and Cu +2 from aqueous solutions.This paper incorporates the effects of dose, concentration and pH.Adsorption of heavy metal on adsorbents was found to increase on decreasing initial concentration, the sorption capacity strongly increased with pH in the range 3-4. The results showed that the removal of heavy metals, such as Fe +3 and Cu +2 from aqueous solution was efficient using peanut hulls as bioadsorbent. The adsorption percentage of Fe +3 and Cu +2 ions by peanut hulls were very high. The Langmuir isotherm model was the best to describe the experimental data. The maximum sorption capacity was found to be 79.28 and 96.58 mg/g for Fe +3 and Cu +2 , respectively. Over all, the present findings suggest that peanut hulls are friendly environmental bioadsorbent, efficient and low cost biosorbent which represents an excellent potential for Fe +3 and Cu +2 removals from aqueous solutions.
