A Brief Review on the Removal of Fe2+ Ions from Water Environment by INDION 220 Na Resin

All living organism on this earth chiefly depends on essential and vital elements like carbon, hydrogen, oxygen, nitrogen, phosphorous, sodium, potassium, calcium, magnesium, iron, manganese, and others; for their growth and survival. Water is universally considers as food for all living beings and all waters, whether natural occurring and/or groundwater(GWs) contains significant amounts of Fe2+in them This cation is ubiquitous regarding the beneficial and ill-health of human beings and significant amount of Fe2+ in water pose several potential socio-economic and socio-wellbeing effects to human. So, the modern society seeking GW as source for various consumption purpose (domestic and/or industrial), considerable technological efforts in softening the inevitable hard water. In spite of the availability of plenty of advanced softening techniques, the conventional ion exchangers are still being adopted, of course with the blended version with novel technologies due their public acceptability and demands. Varieties of resins are being made to suit the requirements of diversified consumers. The applicability of ion exchangers–cum-electrochemical methods might be successful in the years to come. The commercial available cation exchange resin INDION 220 Na was properly dried at room temperature, sieved to appropriate sizes, thoroughly washed in distilled water, and later stored in clean glass containers under moist condition .The investigation was done by using fixed bed reactor(FBR) systems under room temperature. Few preliminary investigations were conducted to assess the appropriate size of resin, in FBR system. The fixed-bed studies covered the important experiments such as generation of breakthrough curves (including the effects of initial Fe2+ concentration, resin size, and flow rate).
