A review on progress of heavy metal removal using adsorbents of microbial and plant origin.

摘要: Heavy metals released into the water bodies and on land surfaces by industries are highly toxic carcinogenic in nature. These heavy create serious threats to all flora fauna due their bioaccumulatory biomagnifying nature at various levels of food chain. Existing conventional technologies for metal removal witnessing a downfall high operational cost generation huge quantity chemical sludge. Adsorption adsorbents appears be potential alternative technologies. Its low cost, efficiency, possibility adsorbent regeneration reuse recovery ions purposes have allured scientists work this technique. The present review compiles exhaustive information available utilization bacteria, algae, fungi, endophytes, aquatic plants, agrowastes as source adsorption process from medium. During last few years, lot has been conducted development after modification with physical techniques. is complex affected operating conditions. As evident literature, Langmuir Freundlich most widely used isotherm models, while pseudo first second order popularly studied kinetic models. Further, more researches required continuous column system its practical application wastewater treatment.
