“…Therefore, in such a case, the cation is in fact a negative complex, which may adsorb very well on a positively charged surface and that happen in this study. As showed when pH values were low, the cation exchange mechanism between tetracycline cation and positively charged Co 3 O 4 was predominant [24][25]. Fig.…”

Tetracycline adsorption on the surface of cobalt oxide studied in this work to determine the appropriate conditions for increasing the efficiency of adsorption by changing the temperature, adsorbed dosages, concentration, contact time and pH. The results showed that the rate of adsorption decreased by increasing the temperature and concentration and at 45 minutes with 0.1 gm of Co 3 O 4. The influence of pH on adsorption at pH (1.2, 6, 8) was studied and concentration with a linear range of (20-70 mg/l), the adsorption ratio decreased by increasing the concentration at the same pH. The point of zero charges pHzc calculated and found to be equal to 7.2. Both Langmuir and Freundlich isotherm studied. The result showed a good agreement with Freundlich linear model.

“…The largest granules (1-2 mm) with high wettability were produced with a 3/7 combination ratio of CW and L. This ratio was used for the production of the granules studied. The use of PVAc as the binder allows the formation of granules with high strength and size more than 1-2 mm compared to previous studies [133,233].…”

In this work, the adsorption mechanism of p-cresol from aqueous solution onto mesoporous activated carbon was investigated. The mechanism of the adsorption process was determined from Weber-Morris and Boyd models. By graphical and statistical analysis was demonstrated that both film-diffusion and intra-particle diffusion are concurrent in adsorption mechanism. The adsorption mechanism of p-cresol onto mesoporous activated carbon was sustained by FTIR analysis, Boehm titration and the point of zero charge of the GAC.
