“…Therefore it is assumed that limited adsorption St (mg/g) St (mg/g) capacity of the adsorbent up to S max (9.86 mg/g), which is comparable with other related studies using ferric modified organic adsorbents or inorganic reagents (Lorenzen et al, 1995;Singh et al, 1996). However, the adsorption capacity is lower when compared to biomass modified with cationic polyelectrolyte (Loukidou et al, 2003). The mechanism of As (V) adsorption on the surface of amorphous Fe (III) oxyhidroxides involves both inner and outer sphere complexation (Goldberg and Johnston, 2001;Jonsson and Sherman, 2008).…”

“…Nowadays, there is a trend to use the alternative and low-cost materials for arsenic removal from the waters in laboratory or medium-scale experiments. Effectiveness of chemically modified or native biomass in processes of arsenic removal was evaluated and proved by various authors (Abdel-Ghani et al, 2007;Boddu et al, 2008;Cernansky et al, 2007;Loukidou et al, 2003;Malakootian et al, 2009;Murugesan et al, 2006;Rahaman et al, 2008;Seki et al, 2005).…”

ABSTRACT:Arsenic is a ubiquitous element in the environment and occurs naturally in both organic and inorganic forms. Under aerobic condition, the dominant form of arsenic in waters is arsenate, which is highly mobile and toxic. Arsenic poisoning from drinking water remains a serious world health issue. There are various standard methods for arsenic removal from drinking waters (coagulation, sorption, ion-exchange reactions or methods of reverse osmosis) and alternative methods, such as biosorption. Biosorption of arsenic from natural and model waters by native or chemically modified (with urea or ferric oxyhydroxides) plant biomass prepared from sawdust of Picea abies was studied. The kinetic of the adsorption process fitted well the pseudo second order adsorption model and equilibrium was achieved after 2 h. The results showed that biosorption was well described by both Langmuir and Freundlich isotherms. The maximum biosorption capacity of the sawdust modified with ferric oxyhydroxides, evaluated by Langmuir adsorption model, was 9.259 mg/g, while the biosorption capacity of unmodified biosorbent or biosorbent modified with urea was negligible. The adsorption capacity is comparable to results published by other authors, suggesting that the prepared chemically modified biosorbent has potential in remediation of contaminated waters.

“…Among all the approaches proposed, adsorption is one of the most popular methods and is currently considered as an effective, efficient, and economic method for water purification. The adsorbents used include activated carbon (Nouri et al, 2002;Pereira et al, 2003), clay minerals (Celis et al, 2000;Abollino et al, 2003), zeolites (Oliveira et al, 2004), metal oxides (Wu et al, , 2005Zhang et al, 2007a), agricultural wastes (Robinson et al, 2002), biomass (Loukidou et al, 2003) and polymeric materials (Atia et al,2003).…”

As an effective, efficient, and economic approach for water purification, adsorbents and adsorption processes have been widely studied and applied in different aspects for a long time. In the recent years, a lot of novel adsorption processes have been developed for enhancing the efficiency of removing the organic and inorganic contaminants from water. This article reviews some new adsorbents and advanced adsorption methods that specialize in their compositions, structures, functions, and characteristics used in water treatment. The review emphasizes adsorption/catalytic oxidation process, adsorption/catalytic reduction process, adsorption coupled with redox process, biomimetic sorbent and its sorption behaviors of POPs, and modified adsorbents and their water purification efficiency.

“…There are three principle advantages of biological technologies for the removal of pollutants; first, biological processes can be carried out in situ at the contaminated site; Second, bioprocess technologies are usually environmentally kind (no secondary pollution) and third, they are cost effective (Loukidou et al, 2003). In looking at waste or wastewater as resource, Sim (2014) highlighted the need to explore bio-effluent in reclamation for non-potable reuse of wastewater, or biosolids in nutrient recovery and soil amendments as well as biogas for renewable energy generation.…”

This review focuses on issues surrounding wastewater management as part of the National Sustainable Development under the Malaysian Mega Science Framework. In line with the national priority area of water security, this review will highlight the technical reports compiled by the Academy of Sciences Malaysia (ASM) on the challenges of water resource development and wastewater management and treatment. The discussion will dwell on the social impact of pollution in water and wastewater and mitigation plans that need to be put in place to ensure sustainable national development and making water as a National Key Economic Area (NKEA).
