Use of Mediterranean plant as potential adsorbent for municipal and industrial wastewater treatment

摘要

A batch adsorption system using driedCarpobrotusedulisplant as a new cheap adsorbent was investigated to remove some pollutants from raw wastewater. The results show that the uptake of nitrate, phosphate and some heavy metals ions from wastewater byC. edulisincreased with increasing contact time. The percentage uptake of heavy metals from industrial wastewater byC.edulisparticleswas about ~94% for Cd(II), ~91% for Cu(II), ~99% for Pb(II) and ~98% for Zn(II). The removal percentage of phosphate and nitrate ions from municipal wastewaters by driedC.eduliswas found to be ~96 and ~97%, respectively. The results indicate that the chemical oxygen demand values decreased after contact with micro-particles of driedC.edulisplant. The maximum uptake capacity was depending on the type of wastewater as well as the type of pollutant.
