Wastewater treatment by adsorption onto Carpobrotus edulis used as natural adsorbent

Journal Title: International Research Journal of Applied and Basic Sciences - Year 2016, Vol 10, Issue 8

Abstract

The aim of the present paper is to study the efficiency of a new process for wastewater treatment by adsorption onto micro-particles of dry plant using the batch equilibration technique. These micro-particles are obtained from grinded and dried Carpobrotus edulis plant. The results show that the micro-particles of C. edulis plant present a good retention of heavy metals, nitrate and phosphate ions from real wastewater. This retention increased with increasing of contact time. The removal percentage of heavy metals from industrial wastewater by C. edulis particles was 94 % for Cd(II), 91 % for Cu(II), 99 % for Pb(II) and 98% for Zn(II). The maximum adsorption capacity was depending on the type of ions (atomic weight, ionic radius and structure…). The results indicate that the chemical oxygen demand (COD) values decrease after contact with micro-particles of dry C. edulis plant. The results obtained are compared with those obtained from -i) distilled water and -ii) from laboratory solutions with various concentrations. These results indicate that the micro-particles obtained from grinded and dried C. edulis plant could be used for removal of heavy metals and pollutant minerals from wastewater.
