| 中文摘要: |
| 研究了超声温度、超声时间、吸附时间、pH值及活性炭负荷比等对含镉废水处理效果的影响。以去除率为考察指标,依据L16(44)正交表进行实验,石墨炉原子吸收法测定处理前后溶液中镉含量,并对测定结果进行直观分析和方差分析。经正交实验优选的条件:超声温度为40℃、超声时间10 min,吸附时间10 min、pH=6、活性炭负荷比为667:1。对优选的实验条件进行方法学考察,各项考察结果均符合要求。结果表明,该方法切实可行,具有简单、高效、快速等优点。 |
| 英文摘要: |
| The present study investigated the effect of ultrasonic temperature and duration, adsorption duration, pH and load ratio of activated carbon on the treatment of Cd-containing wastewater.L16(44) orthogonal test was adopted.Using removal rate as indicator the content of Cd was measured with graphite furnace atomic absorption spectrometry and Square-error analysis as well as direct analysis on the measurement were carried.The optimal condition of the orthogonal test was as follows: ultrasonic temperature was 40℃;ultrasonic and adsorption lasted for 10min respectively;pH=6;load ratio of activated carbon was 667:1.The results of methodological investigation for the optimum conditions were consistent with the requests.The method proved to be practical, simple, efficient and rapid. |
