Kinetics and Adsorption Studies of Tetracycline from Aqueous Solution Using Melon Husk
Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2018, Vol 11, Issue 2
Abstract
The adsorption of tetracycline from aqueous solution was carried out using melon husk as a low-cost adsorbent. The adsorbent was characterized using standard methods and values obtained were; pH = 7.80, bulk density = 0.43 g/mL, ash content = 2.2 %, moisture content = 8.27 %, attrition = 1%, and iodine number = 552 mg/g. Adsorption capacity was found to vary with initial concentration, adsorbent dosage, pH, contact time and temperature, the maximum adsorption capacity in each case was found to be at; 30 mg/L for concentration, 0.8 g for adsorbent dose, 5 for pH, 60 minutes for time and 30 °C for temperature. FTIR analysis was done to analyses the surface functional groups which shows a shift in the intensity the functional groups after the adsorbent was contacted with adsorbate indicative of an adsorption phenomenon,SEM analysis carried out revealed a rough and smooth morphology of the uncontacted and contacted adsorbent respectively. The experimental data judging from the R2 values fitted best into the temkin isotherm. The fitting of tetracycline adsorption in to the pseudo second order kinetic model (R 2 of 0.9992).This result implies that melon shell is a good adsorbent for the removal of tetracycline from aqueous solution.
