Organobentonite for Sorption and Degradation of Phenol in the Presence of Heavy Metals

Isolation and characterisation of phenol-degrading Pseudomonas aeruginosa MTCC 4996

“…The degradation of phenol in the presence of up to 1.0 mM of both Fe and Cu, 1.5 mM Cd and Pb, and 2.0 mM Zn, Mn and Ba in the present study may be due to the fact that microbes display a large range of tolerance and resistance to heavy metals (Trevors et al 1985). Similarly, Yoo et al (2004) reported that addition of both Pb and Cd did not exhibit any inhibitory effect on the degradation of phenol. However, other metals, such as Fe, Cu, Pb, Zn and Mn, stimulated and enhanced the rate of phenol degradation in the present study.…”

Simultaneous sorption of benzene and heavy metals onto two organoclays

“…Few studies have investigated competitive sorption between the metal and organic contaminants to modified bentonites. Past work has focused on only two metals (Pb and Cd) and partitioning-type organoclays [18,19] with only one study of metal/organic competition on an adsorptive clay [20]. More work is needed to characterize the sorption of different metals on both adsorptive and partitioning-type organoclays in the presence of organic solutes in order to more fully understand the potential for, and effect of, competition.…”

A review of the performance of geosynthetics for environmental protection

“…Recently, several studies addressed the potential for sorption of phenolic compounds onto bentonites or organobentonites (Banat et al, 2000;Yoo et al, 2004;Hameed, 2007;Richards and Bouazza, 2007;Malusis et al, 2010;Ahari et al, 2011). As stated above, Ahari et al (2011) obtained nonlinear adsorption curves for bentonite, so they used the Freundlich model to model bentonite.…”
