This bioactive behaviour was accompanied by gradual degradation in PBS, with a 15 % weight loss over 21 days, indicating suitability for bone regeneration. In addition, ICP-OES analysis demonstrated ionic exchange from the scaffolds into the culture medium at both concentrations of 15 mg/mL and 30 mg/mL, which promoted the proliferation of 3T3 fibroblasts.

The development of sustainable techniques to reduce water pollution was urgently needed because dye effluents constituted a major hazard to both the environment and human health. This paper described a simple process for producing cotton stalk-activated carbon (CSAC) using H<sub>3</sub>PO<sub>4</sub> activation and agricultural waste (cotton stalks). The CS impregnation ratios of 1:1 and 1:2 were prepared, and they were named CSAC1 and CSAC2, respectively. Using a range of analytical methods, the produced materials' physical-chemical characteristics were examined. The prepared CSAC2 had a BET specific surface area of 461 m<sup>2</sup>g<sup>−1</sup>. Additionally, CSAC2 material was employed for the adsorption of Rhodamine B (RhB) dye from aqueous solutions. However, the parameters of time, pH, dose, and dye concentration on the removal efficiency of dye were assessed. The isotherm modeling of the adsorption data over the concentration range (20–100 mg/L) was performed using non-linear regression analysis. In addition, it was shown to have >99.5 % removal efficiency and the adsorption isotherms of dye were significantly described by the Langmuir model with maximum adsorption capacities of 144.36 mgg<sup>−1</sup> for RhB. The kinetic modeling revealed that the experimental data followed the pseudo-first order and pseudo-second order rate equations for CSAC2.
