Boosted Removal of Sulfadiazine Drug Using Multiwall Carbon Nanotubes and Comparative with Other Adsorbents

Multiwall carbon nanotubes (MWCNTs) treated and oxidized with sulfuric acid were utilized as a higher adsorbent for fast removal of sulfadiazine hydrochloride (SFD) drug from aqueous solutions. The effect of different important parameters like equilibrium time (۵-۶۰ min), temperature ۱۰-۴۰ oC, pH (۳-۱۰), adsorbent dosage (۰.۰۰۱-۰.۰۵ g), and concentration of drug (۱۰-۱۰۰ mg/L) were well studied and optimized. As a result of the value optimization of different factors such as equilibrium time ۳۰ min, temperature ۳۰ ᵒC, solution pH ۳, concentration of drug ۵۰ mg/L, and weight of MWCNT ۰.۰۳ g. The adsorbent MWCNT was characterized via FE-SEM, TEM, and EDX analyses. The development of MWCNT shows a better potential (removal percentage ۹۷.۲۹% and adsorption capacity Qe ۱۶۲.۱۵ mg/g) within ۱ hr for best drug removal from aqueous solution. The isotherm result was found fitted and in best agreement with the isotherm Freundlich model. The higher and fast removal of drugs was done using MWCNTs in a very short period of time, and the best adsorption efficacy of the developed adsorbent in comparison with developed adsorbent establishes the importance of this research.
