  Laterite soil samples were studied to monitor their efficiency in removing arsenic from contaminated water by adsorption filtration method in laboratory condition. Prepared 10 mg L-1 solution of As3+/As5+ was passed through the six soil samples. At room temperature, a batch of three different samples adsorbs 1010, 925 and 932.5 mg kg-1 of arsenic and their removal efficiency were found to be 58.74, 65.32 and 65.39%, respectively. At 100 °C temperature, the three specimens studied show the adsorptivity of 54.40, 63.47 and 58.69%, while the respective amount adsorbed was calculated 848, 694 and 760 mg kg-1, respectively. Studied IR spectra of the sample of different temperature gradients revealed that the efficiency of a particular composite is high temperature sensitive and the most important and noticeable performance of soil samples is observed when the samples are treated at room temperature, this is the optimum temperature for these soil samples. Above this temperature the efficiency decline gradually.
