Abstract
This study was carried out to be another step towards betterment and development of new ways to
treat perilous problem of arsenic in water which is causing many diseases and other problems to
human life. As in this study various determination methods were utilized followed by each other
in process, due to presence of arsenic in micro level, most of the processes were unable to show
prominent results when quantified by mean of Jasco spectrophotometer. The only result bearing
process was found to be calorimetric and spectrophotometric process of determination of arsenic
by Molybdenum blue method (Vogel and Jeffery 1989). Fractions of Arsenic concentrations as,
20 ppb, 40 ppb, 60ppb and 80 ppb were prepared by dissolving Arsenic(III) Oxide in distilled
water and all the concentrations were treated by the said method and their absorption were recorded
as 0.0934, 0.2671, 0.322 and 0.4600 respectively. Graph was plotted against absorbance vs.
concentration. Given results shown clear increase in absorbance exactly as the fashion of arsenic
concentration. After the detection of arsenic the 80ppb and 60ppb concentration samples were
treated by dipping bark of Vachellia karro (Kikar tree) and Azadirachta indica (Neem Tree) bark
in the sample (respectively) for 3 hours and then resulted effluent was tested again by previously
utilized method for arsenic determination.
