Abstract
Industrial waste inorganic pollutants are normally produced from mineral compounds, such as for example heavy metals, salts, and minerals. These inorganic pollutants can be managed by selecting the appropriate removal techniques. By implementing the removal technique, the number of contaminants may decrease as pollutants reach the soils during certain reaction periods because of chemical reactions and sorption. These reactions depend on both the additive removal material in use, the soil and the environment's chemical characteristics. In soil contamination, reaction rates can be experimentally monitored, and the adsorption mechanism can be measured. The aim of this paper is to experimentally observe the mechanism of heavy metal removal of cadmium chloride in contaminated residual soils using carbon nanotube (CNT) adsorbent. In this research, a series of multi-wall carbon nanotube (MWCNTs) adsorption experiments were used to evaluate the adsorption of residual soil contaminants Cadmium chloride with a concentrations range of 50-200 mg / L. The tests were conducted with different weights of MWCNTs and a concentration of 50 to 200 mg / L of Cadmium Chloride contaminant. The temperature was thoroughly investigated on kinetics and the equilibrium of sorption contaminants in MWCNTs. It shows that MWCNT's can be used to remove heavy metal pollutants, evaluated based on the adsorption mechanism of Langmuir and Freundlich's isotherm models, from the contaminated residual soil as an effective adsorbent. As regards adsorbent models, the balance data in the Freundlich equation are reasonably proven compared to the Langmuir isotherm. As regards adsorbent models, the equilibrium data in the Freundlich equation are reasonably proven compared to the Langmuir isotherm.
