In this research, the resulsts of bentonite characterization by XRF before and after adsorption are presented. The influence of temperature and pH on the capacity and efficiency of adsoption of lead (II) ions using bentonite is determined by adsorption experiments for initial lead (II) concentrations of 200, 300 and 400 mg/L, adsorbent dosage of 1 ...

Fuels are substances that release heat energy during combustion due to the oxidation process that occurs. In order for a substance to serve as fuel, it is important that it has a high calorific value, which is most affected by the carbon content. Sulfur has a very small effect on this characteristic of the fuel but is considered as a negative compo...
