【摘要】 以NiSO₄和NaOH为原料,采用控制溶液结晶法制备球形β-Ni（OH）₂的过程中,通过加入添加剂降低了Ni（OH）₂中SO₄^2-2含量。考察了pH值、Ni²⁺浓度、NiSO₄溶液流速、碱浓度、搅拌强度等因素对Ni（OH）₂中SO₄^2-含量的影响。更多还原

【Abstract】 Using NiSO₄ and NaOH as raw materials, spherical β - Ni（OH）₂ was prepared through "controlling solution crystallization" method. The content of SO₄²- in Ni（OH）₂ product was reduced by adding additives. The relations between pH value, concentration of Ni²⁺, flow rate of NiSO₄ solution, concentration of NaOH, stirring intensity and the content of SO₄²- in Ni（OH）₂ product was investigated.更多还原
