摘要
用十二烧基磺酸钠（SDS）、双氧水对骨炭进行改性.研究骨炭粒径、温度、PH、反应时间等对骨炭吸附废水中Zn（ Ⅱ ）效果的影响.结果表明,随着吸附时间增加,骨炭对Zn（ Ⅱ ）的吸附量逐渐增大,当吸附时间为120 min时,吸附达到平衡.在pH为2-7 时,随着pH的增大,吸附效果逐渐增加.且SDS改性骨炭对Zn（ Ⅱ ）有较好的吸附效果.
The objective of this study was to modified bone char by sodium dodecyl sulfate( SDS) and hydrogen peroxide. The effects of bone char's particle size,temperature,pH,reaction time for bone char adsorption on Zn( Ⅱ) in the waste water was researched. Results showed that with the increase of the adsorption time,the bone char adsorption on zinc increases gradually. When the adsorption time was 120 min,the adsorption equilibrium is reached. When the pH value was 2 ~ 7,the adsorption effect increased with the increase of pH. The bone char modified by SDS has good adsorption effect on zinc.
