ZrO₂ (Zirconia) nanoparticles (NPs), PANI (polyaniline), and ZrO₂/PANI nanocomposites (NCs) were successfully synthesized using CTAB (Hexadecyltrimethylammonium bromide) and SDS (Sodium dodecyl sulfate) surfactants by following the co-precipitation method. The structural phase analysis of as-prepared, annealed nanoparticles, and nanocomposites was done using the XRD (x-ray diffraction) technique. The crystallite size of pure SDS and CTAB assisted ZrO₂ NP_S comes out to be 19 and 17 nm, respectively. After the formation of NCs, the size has been reduced to 15.7 and 15.9 nm, respectively for the same samples. The effect of surfactants on the dye adsorption mechanism was studied using XRD and UV–vis spectroscopy. The prepared NPs and NCs were utilized as an adsorbent for the removal of organic dye methylene blue (MB) which is used as a model compound. UV–vis spectra of the supernatant solution were taken and studied to detect the relative decrease in the dye concentration with time. The as-prepared CTAB assisted ZrO₂/PANI NCs show higher adsorption activity than annealed CTAB assisted ZrO₂/PANI whereas a reversal trend in the adsorption activity was observed for SDS-assisted ZrO₂/PANI NCs. Various kinetic models were implemented and correlated to the experimental data to elucidate the working mechanism for dye adsorption and to set up, a relation in the adsorption activity of surfactant modified NPs and NCs.

通过共沉淀法使用CTAB（十六烷基三甲基溴化铵）和SDS（十二烷基硫酸钠）成功合成了ZrO ₂（锆石）纳米颗粒（NPs），PANI（聚苯胺）和ZrO ₂ / PANI纳米复合材料（NCs）。使用XRD（x射线衍射）技术对制备的退火纳米颗粒和纳米复合材料进行结构相分析。纯SDS和CTAB辅助ZrO ₂ NP _S的微晶尺寸分别为19和17 nm。NCs形成后，相同样品的尺寸分别减小到15.7和15.9 nm。使用XRD和UV-vis光谱研究了表面活性剂对染料吸附机理的影响。所制备的NP和NCs被用作吸附剂，以去除用作模型化合物的有机染料亚甲基蓝（MB）。上清液的紫外可见光谱进行了研究，以检测染料浓度随时间的相对下降。制备的CTAB辅助ZrO ₂ / PANI NCs的吸附活性高于退火的CTAB辅助ZrO ₂ / PANI的吸附活性，而SDS辅助ZrO ₂的吸附活性却出现了逆转趋势。/ PANI NCs。实施了各种动力学模型并将其与实验数据相关联，以阐明染料吸附的工作机理并建立表面活性剂修饰的NP和NCs的吸附活性之间的关系。
