C 32 H 32 Mn 2 N 8 O 12 ,orthorhombic, Pccn (no. 56), a =13.028(2) Å, b =19.081(3) Å, c =7. Source of materialMn(CH 3 COO) 2 · 4H 2 O(0.123 g, 0.5 mmol) and 4,4'-bipyridine (0.96 g, 0.5 mmol) were refluxed in anhydrous methanol (10 ml) for 50 min, then, cyanoacetic acid (0.88 g, 1mmol) was added. The pH value was adjusted to 3with 0.5 MCH 3 COOH solution. The mixture was further stirred for 2h,then filtered. The resulting clear solution was diffused with diethyl ether vapor at room temperature for two weeks. Dark green crystals were obtained, collected by filtration and dried in air (yield, 0.156 g, 37 %). Elemental analysis -found: C, 46.48 %; H, 34.59 %; N, 13.46.%; calculated for C32H32N8O12Mn2:C ,4 6.27 %; H, 34.88.%; N, 13.49 %. IR data are available in the CIF. Experimental detailsThe positions of the water hydrogen atoms were found from Fourier difference synthesis and refined isotropically. The remaining hydrogen atoms were generated theoretically, and included as fixed contributions without futher refinement.

“…One of the significant elements that contribute significantly to the water pollution is zinc. Zinc is one of the essential elements of enzymes, such as superoxide dismutase (Mukhopadhyay et al 1998). The Comprehensive environment response, Compensation and Liability act-2007 (CERCLA) has ranked zinc at 74th position with respect to water pollution with total score of 932.89 points (Mishra et al 2010).…”

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.
