“…Effects of metal concentration on adsorption are presented in Figure 1. Obtained trend is consistent with previous results in the literatures [20,[22][23][24][25][26][27][28].These authors all reported increased adsorption with increasing metal ion concentration. Freundlich and Langmuir isotherm models were used to adjust experimental data (Table 3).…”

The widespread use of heavy metals in different manufacturing processes has resulted in their presence in the air, soil and aquatic ecosystems. Many manufacturing processes release their effluents into nearby streams and rivers due to non-availability of waste treatment technologies in the developing world. Industrialization has therefore been reported to be a major anthropogenic source of these elements and their compounds waterbodies. Conventional methods that are currently being used in the developed world (such as chemical precipitation, ultra-filtration, reverse osmosis, etc) are expensive and so, unaffordable to small-scale businesses prevalent in developing economies. The need for alternative, cheaper and available technologies therefore, cannot be over-emphasized. This study attempted to remove heavy metals (Cu 2+ and Cd 2+ ) from simulated and industrial (paint and textile) wastewaters using sugarcane biomass. A synthetic resin (Chelex) was used as control. Batch sorption experiments were conducted to assess the influence of contact time, adsorbent dose, adsorbate concentration, pH, agitation speed, temperature and particle size. Increases in the parameters (except particle size) gave corresponding increases in percentage adsorption of both metals. Optimal temperature for adsorption was achieved at 50 o C above which adsorption declined considerably. Experimental data for Cu 2+ and Cd 2+ fitted well into freundlich and langmuir isotherms. In textile effluent, 100% adsorption was achieved for both metals using sugarcane biomass in contrast to 89% and 91% for Cu 2+ and Cd 2+ respectively in chelex, a synthetic resin. Similarly, adsorption was 100% for both metals using the biosorbent. Sugarcane biomass may therefore be utilized for water and wastewater remediation in the developing world. Its biodegradability gives comparative advantage over alternative synthetic and expensive resins since its disposal will be more environmentally friendly.

“…Similarly, a positive correlation between the accumulated Cd by green algae and the concentration of free Cd in the solution has been described by Wang and Dei (2006) Klimmek et al (2001) and (48 h) by Zeng et al (2009) studies. Cadmium is a major metal pollutant due to its toxicity.…”

“…In another cyanobacterium, Nostoc muscorum, Singh et al (1992) reported that a 2 to 3× increase in medium P concentration promoted Ni accumulation after culturing cells for 6 d. However, the P concentration (58 to 174 µM) used in their experiments was relatively high compared to realistic P levels in natural waters. Recent studies also suggested that the metal-binding abilities of the cyanophyceaen Lyngbya taylorii for Cd, Pb, Ni, and Zn could be improved by phosphorylation of the alga, which may be important in wastewater purification using this group of algae (Klimmek et al 2001).…”

We investigated the influences of different nutrient regimes on the accumulation of Cd, Zn, and Se(IV) in the freshwater green alga Chlamydomonas reinhardtii over a 4 h exposure period. After the cells had been acclimated to different ambient P levels from 0.1 to 10.0 µM for 2 d in different media (buffer, basic and simplified uptake media), their intracellular metal concentrations increased by 3.6 to 14× for Cd and 1.6 to 4.0× for Zn. Se uptake was, however, decreased by 7.7 to 44×. Semi-continuous culture experiments further demonstrated that the alga's metal concentrations were enhanced 26× for Cd and 8.0× for Zn, whereas Se accumulation was inhibited 75× at the same medium P levels. The uptake rates in semi-continuous cultures increased by 269× for Cd and 11× for Zn, but Se uptake decreased 92× with increasing P concentration. Medium P additions also significantly increased intracellular partitioning for Cd and Zn, but there was no apparent effect for Se. For P-starved or P-repleted cells, the P-enriched medium dramatically increased the cellular accumulation of Cd and Zn compared with the P-depleted medium. A surge uptake of Cd and Zn occurred in P-starved cells. P starvation also resulted in a remarkable increase in Se accumulation in the Pdeplete medium. N enrichment from 5 to 200 µM significantly increased the alga's uptake and intracellular partitioning for Cd and Zn, although the effects were not strictly concentration-dependent. Our study strongly suggests that ambient P enrichment greatly stimulates Cd and Zn accumulation and sequestration in C. reinhardtii, presumably due to rapid P uptake and subsequent formation of polyphosphate in the cells, and distinctly inhibits Se uptake possibly due to the competition of similar anionic forms for transport between Se and P.

When the phytoplankton are under P-limited conditions, the uptake system for phosphate in cells is highly activated. Abrupt exogenous P enrichment results in a rapid P incorporation and storage in intracellular polyphosphates (Kulaev & Vagabov 1983, Wagner & Falkner 2001. Polyphosphate bodies are considered an important pool for the sequestration of heavy metals by freshwater phytoplankton (e.g. Cd, Hg, Pb, and Zn) (Jensen et al. 1982a). Although metal limitation (e.g. of Fe) in phytoplankton may affect the assimilation of nitrate and phosphate (McKay et al. 2001), the effects of nutrient enrichment or starvation on m...
