Locally available apricot (Prunus armeniaca L.) seed shell wastes were utilized for the preparation of an efficient dye biosorbent. The as-prepared apricot seed shell powder (ASP) was thoroughly characterized using FTIR, SEM-EDX, XRD, BET surface area, and pH_PZC measurements to elucidate its functional groups, as well as its surface texture morphology and charge. The effect of several process variables (such as contact time, biosorbent dosage, pH, temperature, and initial concentration) on the dye uptake capacity was also investigated. Based on the experimental finding, the following optimum process conditions were established in the study: pH 2.0, 0.2 g/L adsorbent mass, 30 °C, and time of 120 min. The BET surface area, pore volume, and average pore size of the ASP were estimated as 97.493 m²/g, 0.0691 cm³/g, and 1.922 nm, respectively. The experimental equilibrium and kinetic data were properly described by the Temkin isotherm and pseudo-first-order kinetics model, respectively. Therefore, the effectiveness of ASP as an acid blue 193 dye biosorbent was established in the study.

当地可获得的杏 ( Prunus armeniaca L.) 种子壳废料用于制备高效染料生物吸附剂。使用 FTIR、SEM-EDX、XRD、BET 表面积和 pH _PZC对所制备的杏子壳粉末 ( ASP ) 进行了全面表征测量以阐明其官能团，以及其表面纹理形态和电荷。还研究了几个过程变量（如接触时间、生物吸附剂剂量、pH、温度和初始浓度）对染料吸收能力的影响。根据实验结果，本研究确定了以下最佳工艺条件：pH 2.0，吸附剂质量 0.2 g/L，温度 30 °C，时间 120 min。ASP的 BET 表面积、孔体积和平均孔径分别估计为 97.493 m ² /g、0.0691 cm ³ /g 和 1.922 nm。实验平衡和动力学数据分别由 Temkin 等温线和准一级动力学模型正确描述。因此，有效性ASP作为酸性蓝 193 染料生物吸附剂在研究中建立。
