In recent years, high demand of antibiotics, triggered rapid development in pharmaceutical industries. ![]() Thermodynamics study revealed enthalpy (ΔH°) = 23.02 kJ/mol confirming DCL physisorption on MCM-41. At optimized parameters, very high %Doxycycline removal of 99% with 2425 mg/g adsorption capacity was observed (max 835.5 mg/g adsorption capacity for Doxycycline is reported in literature). the optimum process parameters were found to be pH = 7.3, m = 0.02 g/L and t = 20 min. ![]() Further, various isotherm models (Freundlich, Langmuir and Redlich-Peterson) were studied to represent the adsorption equilibrium experimental data. At optimized parameters, kinetics and adsorption rate controlling mechanism was studied. Based on this, a suitable model equation and adsorption mechanism was suggested. Parameters ( m, pH and t) interaction, modelling and optimization for %Doxycycline removal and adsorption capacity was performed using Box Behnken Design. Adsorbent dose ( m), Doxycycline solution pH, adsorption time ( t) and temperature (T) were considered as process parameters, and %Doxycycline removal and adsorption capacity were measured as responses of the adsorption. In this study, Doxycycline adsorption on to MCM-41 (not reported earlier) was studied. Development of antimicrobial resistance has been announced as one of the top ten threats to global health in 2019. ![]() its inappropriate disposal can affect human health and aquatic fauna. Antibiotics are bio-accumulating and persistent.
