removal of chromiumfromgroundwater using neemleaves asadsorbent

the effluents of tannery industries are the major source of chromium contamination in thegroundwater. in most of the sub-urban areas ground water is the major source of drinking water. for humanbeing long term exposure to chromium is detrimental. the main objective of this study is to assess thegroundwater contamination and to adopt appropriate methods and to develop suitable techniques either toprevent chromium contamination or to reduce it to very low levels with due consideration to cost optimization.bore well samples were collected from 6 location from the proximity of tannery industry at a distance of 25minterval and at different depth during 2014 in the month of march. to remove the chromium from thegroundwater neem leaves is used as the adsorbent. the column study was conducted to determine the effectof adsorbent to remove the chromium concentration from the ground water. to investigate the influences of bedheight on the performance of chromium adsorption on to the neem leaves in a fixed-bed column. the resultsreveal that the concentration of chromium is high near the tannery industry in chrompet so the studyconcluded that usage of groundwater in chrompet should be avoided.
