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 ...

Stainless steel plays an important role in all emerging technologies. Detrimental effects of inclusions in steel do not only depend on their sizes, shape, distribution, but also on their chemical composition and mechanical properties. For this reason, the control of formation of non metallic inclusions and the characterization presen...

Cement is a mineral hydraulic binder which is formed by sintering (heat treatment) primary minerals of cement clinker at a sintering temperature. In the cement composite only cement releases heat by reaction with water, and image about the amount of heat or about temperature of solid concrete is obtained by determination of the heat of hydration of...
