BIO- REMOVAL OF ALUMINIUM, CHROMIUM AND LEAD FROM LIQUID AND WASTE WATER USING FRUITS OF CORDIA OBLIQUA

摘要

The present invention discloses a novel method for bio-removal of heavy metals from liquid and waste water using fruits of Cordia obliqua. The method involves harvesting fruits of Cordia obliqua followed by separation of mucilaginous mesocarp of the fruit. The separated mesocarp was boiled to dissolve in warm water in a predetermined ratio to form an extract of plant product. This extract is added to waste water and pH, temperature are maintained at predetermined values. After a predetermined interval of time the precipitated metals are filtered to remove toxic heavy metals from waste water effluents.
