Chemical and microbiological studies on leachates from a waste tip.
SOME FACTORS affecting the chemistry and microbiology of waste tips are rainfall, surface water runoff, ground cover, types of tip and types of soil within the tip. Previous studies by Qasim & Burchinal (1970), on both simulated and natural tips, showed that anaerobic activity released CO,, H,, N, and CH,, and from acetone extracted tip solids, they obtained several aliphatic acids, ranging fro...
متن کاملFIXED-BED ADSORPTION OF CONGO RED ONTO TEA WASTE IN THE PRESENCE OF Fe2O3 NANOPARTICLES: AN EXPERIMENTAL AND MODELING STUDY
In this study, tea waste (TW) is employed for the removal of Congo red (CR) from aqueous solutions in a fixed-bed column at 30 °C. The breakthrough curves of the adsorption process of CR on TW at three different flow rates are determined. The results revealed that the breakthrough curves were dependent on flow rates in a manner in which a lower flow rate was in favor of the CR adsorption in the...
متن کاملEXPERIMENTAL STUDIES ON CONGO RED ADSORPTION BY TEA WASTE IN THE PRESENCE OF SILICA AND Fe2O3 NANOPARTICLES
In this work, the adsorption of the anionic dye, Congo red (CR), from aqueous solution by using tea waste (TW) has been carried out at 30 °C. The equilibrium sorption isotherms and kinetics were investigated. The equilibrium adsorption was studied by the Langmuir and Freundlich models of adsorption. The experimental results manifested that the Langmuir isotherm was the best model for the adsorp...
