| description | Operators cannot ignore the radiation hazards arising from nuclear weapons. In this study, batch adsorption experiments were investigated to remove the radioactive isotope Cs-137 from the real radioactive wastewater. The attapulgite natural clay mineral was characterized and adopted as an adsorbent in a batch adsorption system. Equilibrium was reached after 2 h with a Cs-137 removal efficiency of 97% for attapulgite. The kinetics of Cs-137 adsorption on the attapulgite clay surface were evaluated. The pseudo-second-order kinetic model produced an excellent fit with the experimental kinetic data.
HIGHLIGHTS
Very cheap attapulgite clay was used in a batch adsorption system.;
Iraqi attapulgite natural clay proved as an efficient adsorbent for the removal of Cs-137.;
Natural clay was modified and manufactured from a locally available material.;
The real samples of radioactive wastewater containing 137Cs have been treated.; |
