The primary goal of this study is to use kinetics and isotherm investigations to remove the methylene blue dye from wastewater samples using carbon generated from the Zephyranthes citrina (ZC) bulb. The current research takes a novel method by looking at porous, efficient raw carbon from ZC, which was used as an adsorbent. At a temperature of 900°C, the well-dried and finely powdered ZC bulb was carbonised. FT-IR, UV-visible, Scanning Electron Microscopy (SEM), and X-ray diffraction techniques were used to analyse the carbonised crude ZC sample, as well as their adsorption capacity to remove the basic methylene blue (MB) dye from an aqueous sample. Both adsorption isotherm and kinetic approaches are used in adsorption investigations. In the batch mode operation, different adsorbate concentrations and adsorbent amounts were used at different time intervals. The kinetics and adsorption process were evaluated using Lagergren first order, pseudo second order, and intra particle diffusion kinetic models. The findings revealed that the adsorption process follows Lagergren's first-order kinetic model. Based on the results, the highest dye removal (81%) was reached for methylene blue in a solution containing 50 mg of the 50 ml dye after 3 hours. The results showed that the ZC carbon bulb is an effective adsorption material that can also be utilised as a low-cost alternative to absorb dye from an aqueous solution without activation.
