为了使酸性含镍氯化铁蚀刻废液资源化制备的铁黄达到颜料性能指标,通过考察改性剂的种类、改性剂用量、改性p H、改性温度和改性时间对铁黄粉体亲油化度的影响,并通过红外光谱、热分析解析了改性剂在粉体表面作用机理。研究结果表明:在最佳工艺条件下,当改性剂为十二烷基苯磺酸钠、改性剂用量为7%、p H为3.5、温度为30℃和改性时间为30 min时,其亲油化度高达54.7%。红外光谱和热分析显示,十二烷基苯磺酸钠以化学键合的方式结合在纳米铁黄的表面,其包覆量大约为5.4%,使纳米铁黄粉体具有亲油疏水性能。
In order to make the yellow iron ferric hydroxide etching waste resources to achieve the pigment performance index, by investigating the type of modifier, the amount of modifier, modified p H, modification temperature and modification time of yellow iron powder Lipophilicity, and analyzed the mechanism of the modifier on the surface of the powder by infrared spectroscopy and thermal analysis. The results showed that under the optimum conditions, when the modifier was sodium dodecyl benzene sulfonate, the amount of modifier was 7%, p H was 3.5, the temperature was 30 ℃ and the modification time was 30 min , The pro-oleation of up to 54.7%. Infrared spectroscopy and thermal analysis showed that sodium dodecylbenzenesulfonate was bound to the surface of nano-iron yellow by chemical bonding, and the coating amount was about 5.4%, which made the nano-iron yellow powder possess lipophilic and hydrophobic properties.
