Removal of acetaminophen from the contaminated water using adsorption onto carbon activated with NH₄Cl

Abstract

A B S T R A C TThe efficacy of NH 4 Cl-induced activated carbon (NAC) in removing acetaminophen (ACT) as a model of non-steroidal anti-inflammatory pharmaceutical compounds in aqueous solution is investigated in this study. The experiments were performed in different conditions of solution pH, contact time, initial concentration, adsorbent concentration, and solution temperature to the adsorption of ACT on NAC. The results showed that ACT adsorption onto adsorbent was not pH-dependent in the range of 2-9; but, at higher pH values, the removal efficiency was significantly decreased. Adsorption of ACT by NAC followed pseudo-second order kinetics, and the equilibrium adsorption data best fitted the Langmuir isotherm. The maximum capacity was 233 mg/g. Overall, NAC efficiently adsorbed ACT; thus, it can be considered as an affordable and cost-effective system for the removal of pharmaceutical compounds from aqueous solutions.

Adsorption of Fluoxetine and Venlafaxine onto the Marine Seaweed Bifurcaria bifurcata

“…Adsorption on activated carbon is a well-established technology for water treatment owning to its versatility and high efficiency, including for PhCs (Putra et al, 2009;Calisto et al, 2015;Mashayekh-Salehi and Moussavi, 2016). Nevertheless, it is an expensive adsorbent, US $20-22/kg (Babel and Kurniawan, 2003), which limits its widespread applicability.…”

Solubility and degradation of paracetamol in subcritical water

“…7,8 Although paracetamol, used as fever reduction drug and for pain relief, is relatively safe at lower doses, it has various hazards, such as gastrointestinal disease, liver failure, hepatotoxic potential, and centrilobular necrosis in the liver. 9,10 100 E M İ R E et al…”

Adsorption of acetic acid and hydrogen sulfide using NaOH impregnated activated carbon for indoor air purification

“…Among these methods, adsorption with activated carbon is an available removal method for the removal of organic and inorganic pollutants due to its cost‐effective, large surface area, numerous microporous structure, good surface chemistry, and renewability. Up to now, many adsorption studies have mainly focused on the removal of liquid contaminants, such as acetaminophen, dye, and heavy metal . However, studies on the adsorption of gaseous CH 3 COOH on activated carbon have hardly been reported.…”
