以废弃石榴叶提取液等一锅法绿色合成了硫化纳米铁(S-nZVI),制备过程简单。并利用扫描电镜等仪器进行了表征。探讨了其类芬顿(Fenton)法去除水中罗丹明B(RhB)的影响因素。结果表明:当过氧化氢浓度为9.9mmol/L,pH为5,RhB浓度为25mg/L,温度为25℃,S-nZVI悬浮液投加量为84mL时,RhB的脱色效果达93%。相对于纳米零价铁(nZVI),S-nZVI类Fenton法去除RhB的效果更好,且使用寿命更长。空气中常温放置一个月后S-nZVI悬浮液对RhB去除率仍达75%以上。
Sulfurized nano iron (S-nZVI) was green-synthesized by a simple one-pot method from abandoned pomegranate leaf extract,and characterized using scanning electron microscopy and other instruments.The factors influencing the removal of Rhodamine B (RhB) from water using Fenton-like method were explored.The results showed that when the concentration of hydrogen peroxide was 9.9mmol/L,pH was 5,the concentration of RhB was 25mg/L,temperature was 25℃,and the dosage of S-nZVI suspension was 84ml,the decolorization effect of RhB reached 93%.Compared to nano zero-valent iron (nZVI),S-nZVI Fenton-like method had a better effect on removing RhB and a longer service life.The removal rate of RhB by S-nZVI suspension still maintained 75%,after being placed in the air at room temperature for a month.
