Acacia Tortilis Seeds as a Green Chemistry Adsorbent to Clean up the Water Media from Cadmium Cations

Abstract: Abstract-The potential use of Acacia tortilies seeds as a new green chemistry adsorbent to reduce cadmium cations from water was evaluated through batch experiments. The Acacia tortilies seeds were characterized by determination of solubility in water and determination of surface area and pore volume as well as determination of cellulose content. The important parameters which affect the adsorption process, such as initial pH, contact time and contact temperatures were studied. The maximum adsorption capacity … Show more

“…Both biomasses showed positive and low enthalpy values (less than 40 kJ mol −1 ), showing that the adsorption process is physical and endothermic [42]. The entropy energy of the system was reduced and negative, signaling a minimal change in the system, which demonstrates that the adsorption with oil emulsion may not be fully reversible for the biomasses of this study [43]. The Gibbs energy obtained was positive for the three temperatures with the two biomasses, as described in Table 7, proving that the adsorption process is not spontaneous.…”

“…The effect of the pH was studied in the interval from 2 to 6 for a contact time of two hours ; the maximum value of the pH equal to 6 was retained to avoid the precipitation of the cupric ions which would be likely to cause an interaction between the phenomena of adsorption and precipitation of Cu(OH) 2 (Ackacha and Meftah, 2014).…”
