钛铁矿渣制备高效絮凝剂的试验研究王晓峰1，郭清泉1，李大光1，朱文新2（1.广东工业大学轻工化工学院，广东广州510006；2.银星化工有限公司，广东韶关512200）［摘要］以钛铁矿废渣为原料，采用正交实验设计，制备了无机高分子絮凝剂。实验表明最佳合成条件为：酸浸液pH为2.2，反应温度为45℃，聚合时间为2h。探讨了所制絮凝剂对印染废水的处理效果，并借助FT-IR、SEM分析了产品的结构和形貌特征。表明球形、具有掺杂结构、无定型态的聚铁絮凝剂具有良好的絮凝沉积效果。［关键词］钛铁矿渣；絮凝剂；印染废水［中图分类号］TQ314.253［文献标识码］A［文章编号］1005-829X（2011）08-0060-03ResearchandexperimentonthepreparationofhighlyeffectiveflocculantwithilmeniteslagWangXiaofeng1，GuoQingquan1，LiDaguang1，ZhuWenxin2（1.FacultyofChemicalEngineeringandLightIndustry，GuangdongUniversityofTechnology，Guangzhou510006，China；2.SilverStarChemicalCo.，Ltd.，Shaoguan512200，China）Abstract：Withilmeniteslagasrawmaterial，theinorganichighpolymerflocculanthasbeenpreparedbyorthogonaltest.Itshowsthatoptimumsynthesisconditionsareasfollows：thepHofpickleliquoris2.2，reactiontemperature45℃，andpolymerizationtime2h.Thetreatmenteffectivenessofthepreparedflocculantonprintinganddyeingwastewaterisdiscussed，anditsstructureandmorphologycharacteristicsareanalyzedbyFT-IRandSEM.Theresearchshowsthatspheri
