“…Biosorbents have emerged as a particular class of substanc es in adsorption processes due to their abundant availability in natural resources or waste and their commendable perfor mance. Some naturally occurring substances have been exam ined as biosorbents for eliminating dyes within this context, and the data from these investigations showed promising re sults [2]. Prickly pear cacti are ubiquitously present in semi arid regions across the globe and are characterized by their af fordability and accessibility.…”

Purpose. A leading cause of water contamination is the widespread use of dyes, which are consumed in large amounts. The purpose of the present study was to investigate the potential of the Cactus paddle (CP) as an environmentally safe biosorbent for removing Basic Red 46 dye from aqueous media. Methodology. Various analytical tools, comprising XRF, XRD, BET/BJH, FTIR, and pHPZC methods, were used to examine the surface characteristics of the biosorbent. For assessing the ability of CP for BR46 adsorption, batch adsorption assays were performed. Findings. An amount of 3.45 mg · g-1 of BR46 was adsorbed at pH 7, 500 rpm and 293 K within 180 minutes. The isothermal data was described by both the Freundlich and the Langmuir equations with R2  0.984 and 2  0.01. The kinetics was well described by a PSO model, suggesting that physico-chemical interactions govern the adsorption process. Originality. For the first time, the effective use of a local raw material resource CP as a biosorbent for the removal of BR46 dye has been substantiated. Practical value. As a result of the findings of this study, it seems possible that CP can be regarded as a sustainable resource, which would create a possibility for addressing environmental concerns in the future.
