摘　　要：为了延长铝合金阳极氧化液使用寿命,减少污染物的产生,采用离子交换树脂回收铝合金阳极氧化液中的铝资源。以单因素试验为基础,采用响应面优化试验优化树脂吸附和再生工艺参数,同时利用响应面软件Design-Expert8.0.6进行试验设计和模型分析。结果表明:树脂吸附铝离子最佳条件为反应时间10 min、树脂用量360 g/L,铝离子交换率为68.35%;树脂再生最佳条件为再生液浓度4.15%、再生液用量8.57 mL/g、再生时间30 min,树脂再生率为91.07%;树脂经多次循环使用,铝离子交换率和树脂再生率可保持在53%和84%左右。In order to prolong the service life of aluminum alloy anodizing liquor and reduce pollution,aluminum was recovered from the anodi-zing liquor using ion exchange resin.Based on single factor experiments,response surface optimization experiments were conducted to optimize the resin adsorption and regeneration processes,while the experimental design and model analysis were performed using Design-Expert 8.0.6.As a result,the optimal conditions for resin adsorption of aluminum ions were obtained:the reaction time was 10 min,the resin dosage was 360 g/L,and the aluminum ion exchange rate was 68.35%.The optimal conditions for resin regeneration were also obtained:the concentration of the regenerated solution was 4.15%,the dosage of the regenerated solution was 8.57 mL/g,and the regeneration time was 30 min,achieving a resin regeneration rate of 91.07%.After multiple cycles of resin use,the aluminum ion exchange rate and resin regeneration rate were main-tained at around 53%and 84%,respectively.
