Studying the sorption kinetics on peat ions of iron(III) and copper(II) from wastewater

Abstract

The sorption kinetics on the peat of copper(II) and iron(III) ions from model solutions are studied. The sorption process takes place quickly and is almost complete after 20 minutes. Based on the processing of the experimental absorption curves of the equations of chemical kinetics and diffusion it is established that the sorption process is in the diffusion mode. The stage of the chemical interaction of the metal ions with the functional groups of peat also contributes to the overall speed of the process. The efficiency of the sorption process is determined and the possibility of Using peat as a sorbent for purifying wastewater from the copper( II) and iron(III) ions at industrial sites is shown.
