Abstract
The present study deals with the comparison of removal of dyes and metals using natural adsorbents such as rice husk, jack fruit leaf powder, coconut shell etc. The study deals with various research papers in which variety of biosorbents are used for the removal of dyes and metals. The entire working principle uses fixed bed column system for isolating and removing the impurities such as dyes and metals from the water sources. Dyes such as acid dyes, reactive azo dyes, food dyes, crystal violet dyes etc. and heavy metals such as lead, copper, cadmium etc. can also be effectively removed by adopting fixed bed column system through different adsorbing materials. The comparison between the various adsorbents is given in table. The adsorbing materials used here are Activated carbon, Rice husk, jack fruit leaf powder, coconut shell etc.
