Elimination of nickel ions in a packed column using clamshell waste as an adsorbent.

ABSTRACT: The present investigation assessed the viability of utilizing a powdered clam shell in continuous adsorption to eliminate nickel ions from simulated wastewater. The breakthrough curves (BTC) were analyzed by altering the Q (inlet flow rate) in a glass column (ID 5 cm, H 35 cm) with a multi-port and filled with the powdered clamshell adsorbent (PCSA). The PCSA's nickel adsorption efficiency was maximum (87.68%) with Q = 8 mL/min at a bed length (H) of 25 cm with 1.05 mg/g adsorption capacity. Moreover, the mass transfer zone (MTZ) and idle bed length (L_u) were estimated from the corresponding BTC. The values of MTZ and L_u demonstrated fluctuations in response to changes in bed length, suggesting the presence of non-ideal circumstances. The validity of the Thomas model
