Investigation the efficiency of nanocomposite bentonit magnetic on acetaminophen drug removal using ferric oxide nanoparticles

Acetaminophen is one of nearly used analgesics/antipyretics worldwide and Iran country for treating human and animals. Few amounts of antibiotics including acetaminophen are very unsafe for human health and environmental. The goal of this applied-analytical research is to investigate of the possibility acetaminophen drug removal from urban drinking water by utilizing batch nanocomposite bentonit magnetic using ferric oxide nanoparticles reactor. The variables under study involved are the pH, contact time, adsorbent amount, initial acetaminophen concentration, reaction kinetics and nanocomposite bentonit magnetic using ferric oxide nanoparticles characteristics. sample of urban drinking water is prepared containing 25-75 mg/L of acetaminophen. Nanocomposite bentonit magnetic using ferric oxide nanoparticles is prepared in laboratory oven at 70˚C for 24 h. The acetaminophen-containing water is introduced into batch reactor and the acetaminophen removal efficiency is investigated in different conditions for pH (4-10), contact time (0-90 min) and adsorbent doses (0.5-1.5 gr/dl). The characteristics of the Nanocomposite bentonit magnetic using ferric oxide nanoparticles demonstrated that the average diameter in size of the Nanocomposite bentonit magnetic using ferric oxide nanoparticles particles is 48.2 nm. The main component of the Nanocomposite bentonit magnetic using ferric oxide nanoparticles is silica (Si). The best conditions for acetaminophen removal obtained are at pH 4, contact time 30 min, an adsorbent dose of gr, and an acetaminophen concentration of 25 mg/L. The adsorption of acetaminophen on to Nanocomposite bentonit magnetic using ferric oxide nanoparticles is followed Langmuir isotherm model (R2> 0.95). The findings show that acetaminophen reduction efficiency is increased with increasing adsorbent dose, contact time, and decreasing acetaminophen concentration, and pH. This Nanocomposite bentonit magnetic using ferric oxide nanoparticles has suitable proficiency for the acetaminophen removal from water.
