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 (5-60 min), temperature 10-40 °c, ph (3-10), adsorbent dosage (0.001-0.05 g), and concentration of drug (10-100 mg/l) were well studied and optimized. as a result of the value optimization of different factors such as equilibrium time 30 min, temperature 30 °c, solution ph 3, concentration of drug 50 mg/l, and weight of mwcnt 0.03 g. the adsorbent mwcnt was characterized via fe sem, tem, and edx analyses. the development of mwcnt shows a better potential (removal percentage 97.29% and adsorption capacity qe 162.15 mg/g) within 1 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.
