Abstract
Development of nanofilters with the ability to remove toxic metal ions from effluent wastewater will be of immense help to the leather industry. In this study, fibrous nanofilter (FNF) was prepared using microfibrillated cellulose and tea leaf microparticles blended in poly (vinyl) alcohol. FNF was analysed for its efficacy to remove hazardous metals from tannery effluent wastewater. The FNF had promising traits of tensile strength (19.24 + 0.05 Mpa), elongation at break (22.31 + 0.12%), flexibility (10.88 + 0.05%), water absorption (37.86 + 0.14%) and desorption (32.54 + 0.33%). The metal adsorption studies clearly reflected the removal of toxic Cr (VI) ions from the effluent water by FNF. The study establishes an economically feasible and highly efficient way to remove hazardous metal ions from effluent wastewater.

Summary
Leather industries pose a severe threat to the environment owing to the discharge of effluent waste water which contains a wide range of pollutants. Hexavalent chromium (Cr VI) causes potent health hazards, and some salts are considered to be carcinogens (Kolomaznik et al, 2008) In view of this alarming facts, it becomes essentially important to treat the effluent waste water in a cost-effective manner to remove heavy metals and other contaminants, before discharge into the environment. Around “n” number of strategies are practised globally to combat this heavy metal polluted waste water problem viz., adsorption, membrane filtration, chemical precipitation, electrochemical treatment, activated carbon etc. These technologies are highly expensive and time consuming which becomes a great hurdle in their implementation. The study aims to prepare and characterize a fibrous nanofilter using a combination of cellulosic nanofibers, polymeric solution (PVA) and tea waste microparticles and to evaluate its heavy metal adsorption characteristics in tannery waste water
