“…In phases 7 and 8, residual concentration slightly violated the regulatory guideline limit of 0.2 mg/L due to damage on the surfaces of living cells, resulting in the partial loss of sorption abilities and the release of accumulated metal into the solution [16]. Copper can significantly damage the surfaces of living cells which could lead to partial loss of cell binding abilities and release of accumulated copper back into solution [17]. Similar observations was also made by other works [16].…”

Two support materials, microwave incinerated rice husk ash (MIRHA) and groundwater treatment plant sludge (GWTPS), were used as support materials for biomass in the removal of copper from aqueous solution during a continuous flow study. A third reactor containing biomass alone without the addition of support material (RB) was used as a control to monitor the performance of the support materials. All reactors were given 15 days for the acclimatization of biomass. The reactors containing MIRHA and GWTPS were given an additional 10 days for acclimation after the addition of the support materials on day 15. All reactors were identically designed with a size of 8.5 L and operated at a flowrate of 7 L/d and SRT of 30 days across 8 different phases. Different concentrations of Cu(II) ranging from 0.5 mg/L to 15 mg/L were applied to the reactors at different phases. Results obtained from each phase of the experiments showed that GWTPS and MIRHA improved copper toxicity resistance in their respective reactors. For the control reactor (RB), copper toxicity was significant and violated the DOE Malaysia copper effluent standard at phase 5 (influent concentration 2 mg/L) whereas MIRHA and GWTPS reactors violated the DOE Malaysia copper effluent standard at phase 7 (influent concentration 10 mg/L) respectively. However, GWTPS containing reactor showed slightly better support for toxicity resistance than reactor MIRHA. The toxicity of copper on the three reactors was observed in the reduction of mixed liquor volatile suspended solids (MLVSS) within each reactor. For the control, MLVSS rapidly decreased from phase 3 to phase 8 whereas MIRHA and GWTPS reactors increased from phase 3 to phase 6 and decreased from phase 7 to phase 8. These results have shown that MIRHA and GWTPS have the potential of improving biomass resistance to toxicity of heavy metals.

“…These constituents play a diverse role in metal ion binding, i.e., these components create the sites for binding of metal ion. Biosorption process of metal ions is quite fast and independent of cell metabolism (Veglio and Belochini 1997;Kadukova and Vircikova 2005). This process is also known as passive biosorption.…”

Massive industrialization and urbanization of civilization during the last few decades have made a thrust in heavy metal pollution in various water bodies. In past, various kinds of conventional metal ion remediation technologies, such as cementation, osmosis, reverse osmosis, ultrafiltration, etc., have been practised. However, most of these technologies are quite expensive, and lead to the generation of secondary chemical sludge. However, biosorption of heavy metal ions is significantly inexpensive and an eco-friendly technology. Among the series of heavy metals, zinc has gained the significant interest due to its toxicity and easy availability in water bodies. Biosorption of zinc in liquid phase by living, nonliving, conventional and non-conventional biosorbents has been practised extensively in the past. This literature review focuses on the recent trends practised in the field of biosorption of zinc from liquid phase. The present work provides deep insight into various aspects of biosorption of zinc by different mechanisms of biosorption, bioaccumulation, isotherm, kinetic and mechanistic modeling. An exhaustive comparison among different sorts of biomasses has also been given in the present work to enlist all the milestones of biosorption.

“…Therefore, plants may have possibly been in contact with a higher concentration of copper in its free ionic form during the first minutes to hours of the bioassay. Studies on the kinetics of heavy metals uptake by aquatic plants have revealed an initial phase of fast metal removal followed by a lineal slower phase [23] and, in accordance with this, [4] found that S. minima lead and cadmium uptake was 55 % and 60 %, respectively, during the first 4 to 6 hours of their bioassay. May S. minima's copper removal uptake been higher without metal precipitation?…”

Abstract:In order to determine copper removal efficiency and compartmentalization in the free floating fern S. minima, a bioassay was performed in which plants were exposed to increasing copper concentrations in the range of 1 to 30 mg Cu L -1 for six days in Pilcomayo River surface water. S. minima accumulated the metal in a dose-dependent manner. Metal concentration was from 6.5 to 3.9 times higher in the submerged biomass in comparison to the aerial biomass in all treatments reflecting a poor mobility of copper between plant tissues. In both biomasses, most of the copper was localized in the extracellular compartment and increased lineally with increasing concentration of copper in water. The intracellular fraction increased following a polynomial function. The physicochemical characteristics of the experimental water influenced copper bioavailability inducing copper precipitation and the high concentration of calcium may have exerted a protective effect limiting metal entrance to cells. The values of the BCF and of the dry biomass weight that corresponded to copper showed that in Pilcomayo River water S. minima showed a copper removal efficiency not of a hyperaccumulator but of an effective accumulator.
