摘要

Producing cost-effective adsorbents derived from agricultural waste constitutes a successful undertaking technique. In this study, cellulose from Luffa acutangula peels (CLAP) served as an adsorbent for the efficient adsorption of methylene blue (MB), crystal violet (CV), and diclofenac sodium (DS). The properties of CLAP were determined through characterization using various instrumental analyses. This study indicated that CLAP’s maximum adsorption capacities were 263.15 mg/g for CV, 166.6 mg/g for MB, and 153.84 mg/g for DS at their respective optimal parameters. After testing various desorbing eluents (0.1 M), the desorption process revealed that 98.16% CV, 93.66% MB, and 88.60% DS were successfully desorbed. The cost analysis demonstrated that preparing the CLAP and adsorption study was cost-effective (286.95 INR). The results of this study have the potential to lead to progress in the science of cellulosic materials, as well as protection against aqueous contamination.
