In the present work, the potential use of modified linde type a zeolite for removal of arsenic (V) has been examined. The predominant oxidation states of arsenic are As (III) and As (V). A simple & effective method has been proposed to reduce the arsenic from environmental sample. Linde TypeA zeolite was synthesized hydrothermally & characterized by X-ray and FTIR, SEM, PSA. Synthesized zeolite was modified with hexadecyl trimethyl ammonium (HDTMA) to make it capable to exchange Anions. Molar absorptivity of Arsenic was determined at various concentrations by adding 0.25 mg of surfactant modified zeolite using Batch process. Concentration of the solution was determined by molybdenum method having an absorption maximum at 840 nm. All studies were carried out at room temperature result obtained shows that Arsenate ion absorbed effectively up to 70% by surfactant modified zeolite (SMM). Which is comparable or sometimes better than the previous proposed material.Studies were also carried out by using different amount of surfactant modified Zeolites at conc. 50 µg / ml. The optimum condition reached when 0.25 gm of modified zeolite was used. From the study of time dependence of sorption by synthesized modified zeolite it was found that sorption72 % increase up to about 6-7 hr and then it remains more or less constant.
