| 摘 要： | 以废茉莉花茶渣作为吸附剂,对含Cr(Ⅵ)溶液进行了吸附研究。分别考察了吸附时间、茶渣投加量、Cr(Ⅵ)初始浓度、茶渣粒径、温度、pH值等因素对废茉莉花茶渣吸附Cr(Ⅵ)的影响。在吸附时间2 h、茶渣投加量为30 g/L、Cr(Ⅵ)初始浓度为40 mg/L、茶渣粒径60目、pH值2.5时,茶渣对Cr(Ⅵ)吸附率达98.7%。温度越高,茶渣对Cr(Ⅵ)吸附效果越好。废茉莉花茶渣对Cr(Ⅵ)具有较好的吸附能力,是比较合适的重金属离子吸附剂。

| Abstract: | Cr(Ⅵ) was adsorbed with waste jasmine tea dust as adsorbent.The effects of adsorption time,tea dust dosage,Cr(Ⅵ) initial concentration,tea dust particle size,temperature,pH value on Cr(VI) adsorption with waste jasmine tea dust have been investigated,respectively.The adsorption percentage of Cr(Ⅵ) with tea dust obtained 98.7% in the condition of adsorption time for 2 h,tea dust dosage of 30 g/L,Cr(VI) initial concentration of 40 mg/L,tea dust particle size of 60 mesh,pH value of 2.5.The higher the temperature was,the better the adsorption result was.The waste jasmine tea dust has the better adsorption ability on Cr(Ⅵ),which is a suitable adsorbent of the heavy metal ions. |
