研究了十六烷基三甲基溴化铵（CTABr）和十二烷基硫酸钠（SLS）对碱性电积法生产锌粉的电流效率、槽电压、伏安行为和存款性质的影响。采用扫描电子显微镜、X射线衍射仪和马尔文激光粒度分析仪分别对锌粉的表面形貌、晶体学取向和粒度分布进行了研究。当CTABr浓度为1 mg/L时，电流效率最高，达97.5%，SLS浓度为10 mg/L时，电流效率最高，达98.3%。伏安法研究表明，表面活性剂的阴极极化，这反映在粉末的性质。表面活性剂显著改变了表面形貌，减小了晶粒尺寸。在10 mg L−1 CTABr存在下，获得平均粒度为34.7 μm的锌粉。在0-10 mg L-1 CTABr/SLS下，锌粉表现出以（101）（002）（100）为主的取向。1 mg L-1 SLS对Sb的影响有积极的抵消作用。
The effects of cetyltrimethylammonium bromide (CTABr) and sodium lauryl sulfate (SLS) on the current efficiency, cell voltage, voltammetric behavior, and deposit character during production of zinc powder by alkaline electrowinning were investigated. Surface morphologies, crystallographic orientations, and grain size distributions of zinc powders were examined by Scanning Electron Microscopy, X-ray Diffraction, and Malvern Laser Particle Size Analyzer, respectively. Maximum current efficiencies of 97.5 and 98.3% were obtained at 1 mg/L CTABr and 10 mg/L SLS, respectively. Voltammetric studies indicated that the surfactants polarized the cathode, which was reflected in powder character. The surfactants dramatically changed the surface morphology and decreased the grain size. Zinc powders with an average grain size of 34.7 μm were obtained in the presence of 10 mg L−1 CTABr. At 0–10 mg L−1 CTABr/SLS, zinc powders exhibited an orientation dominated by (101) (002) (100). 1 mg L−1 SLS hadapositive effect on counteracting the influence of Sb.
