Preliminary Study of Novel Coal Spills-based Physical Activated Carbon for Copper ions Adsorption in Aqueous Solution: Kinetics and Isotherms

The present work aimed at mitigating the level of copper ions (Cu++) by adsorption in aqueous solution using activated carbon powder (AC) and biosorbent (BS) from the Indian jujube seed hulls. The AC and BS were prepared from the Indian jujube seed hulls and characterized using standard procedures. In addition, the adsorption effects of Indian jujube seed hulls through the AC and BS were carried out using jar test experiment (batch mode) at different pH (1, 2, 3, and 4), ionic strengths (100-600 mg/L) and stirring speed (120rpm). Therefore, it was found that the adsorption time at equilibrium were 10 and 5 minutes respectively for the AC and the BS. Furthermore, it was found that the reduction of copper ions were 99.40% and 73.08% for aqueous solutions of 100 ppm and 500 ppm respectively at the equilibrium state. It was also revealed that when the mass of the AC or the BS increases, the quantities of ions adsorbed per gram decrease. The maximum pH of adsorption for the AC was found to be pH=1, while it was found to be pH=4 for the BS. The Freundlich model indicated that the adsorption of copper ions by the Indian jujube is linear while the Temkin and Dubinin-Kagana-Radushkevich models described the adsorption as a physical reaction. It was finally observed that the adsorption of copper ions by the AC and the BS from Indian jujube seed hulls influenced by the addition of some concentration of NaCl.

Adsorbent Dose

The present experiment explains the effectiveness of adsorption studies of methylene blue dye from aqueous solutions on activated carbon from Selenicereus grandiflorus (SG) treated with conc. sulfuric acid. The sulphuric acid-treated Selenicereus grandiflorus activated carbon (SGAC) was used as low-cost adsorbent for the removal of methylene blue dye from aqueous solution. It suggests an ideal alternative method to adsorption of dye compared to other expensive treatment options. The adsorption studies have been conducted at different experimental parameters, i.e., pH, contact time, adsorbent dose and initial dye concentration. The batch mode experiments were conducted by different adsorbent dose (0.03-0.150 g per 50 mL), pH of the solution (2-12), effect of time (3-18 min), initial dye concentration (10 mg/L), point of zero charge and regeneration of spent adsorbent studies. Langmuir model shows better fit to the equilibrium data (R2 = 0.966) than Freundlich model. The adsorption capacity (Qm) of SGAC increases with increasing dosage where Qm is 16.17 mg g-1.
