| Abstract | ||||
| Organic pollutant substances have direct effect on humans and animals. Wastewater containing organic pollutant like phenol compound can contaminate ground water resource and thus lead to a serious ground water problem. This study present the adsorption technique of (MWCNTs) which is used as adsorbents for the removal of phenol compounds from synthetic contaminated water. Many parameters are studied like pH, agitation speed, contact time and adsorbent concentration to determine their influence on the removal of phenol and on adsorption rate .The concentration of phenol in water before and after treatment was determined (analyzed) using high performance liquid chromatography technique (HPLC).The kinetic studies for adsorption followed the pseudo-second order model. The adsorption isotherm fit with Langmuir isotherm. The optimum conditions using MWCNTs were contact time 120 min, pH 7, agitation speed 130 rpm and dose of adsorbent 0.3 g. The removal percentage was 85.54%. | ||||
