Removal Of Zinc From Synthetic Waste Water By Saw Dust As An Adsorbent

Abstract

The industrial waste water contains highly toxic metal. The heavy metal such as ZnP + Pare highly toxic and harmful for the living organism .different salt of zinc like zinc chloride is responsible for the many hazardous disease .There are so many different technique used for the purification of these waste water and removal of these heavy metal like ion exchange, solvent extraction, precipitation. But all these method are highly expensive and required proper setup to be used. The adsorption is the one of the most inexpensive mass transfer operation which is also used to remove these impurities the commonly used adsorbent used in the industries are activate charcoal or activate carbon which gives good result but highly expensive .There are so many alternative present in our environment which can easily replace this activate carbon with better efficiency .sawdust is one of them as it contain lignin and cellulose which easily traps all the impurities present in the waste water in the form of heavy metal like ZnP + P. The present paper is about the experiment performed and the result showed the maximum removal of ZnP + P ion by sawdust is 90%.
