Abstract
The efficiency of using a composite of carbon black and sodium bentonite in treating drinking water contaminated with lead and copper
ions was analyzed. The effects of pH, contact time, concentration and adsorbent dosage using an adsorbent composite of 20 % sodium
bentonite and 80 % carbon black were studied. The adsorption data was analyzed with respect to Langmuir, Freundlich and Temkin
isotherms. The data fits well with the Langmuir isotherm model with high coefficients of determination for both metal ions adsorption.
The adsorption kinetics follows a pseudo second-order model for both metal ions. The maximum metal ion uptake (qmax) of composite
adsorbent is 7.69 and 0.80 mg/g for lead and copper, respectively.
