温度和吸附时间对竹炭去除有害物质的影响

摘要

This study analyzes the effect of different temperatures and adsorption time on removing harmful substances by bamboo charcoal. Bamboo charcoal has better adsorption performance for TVOC test solution, which has large molecular weight, high boiling point and weak polarity. Temperiture has a signiifcant impact on adsorption performance of bamboo charcoal. In practice, in order to remove harmful substances the optimal adsorption duration of bamboo charcoal is 4 to 5 days.%分析了不同温度、吸附时间对竹炭除去有害物质的影响。研究表明：竹炭对分子量大、沸点高、极性弱的TVOC试验液的吸附性能更高。温度对竹炭的吸附性能影响明显。在实际使用过程中，竹炭除去有害物质的最佳持续吸附时间为4~5d。
