摘要
研究了自制载银竹炭对苯酚的吸附条件与效果。试验结果表明:载银后的竹炭对水相的苯酚仍具有良好的吸附性能。其最佳吸附酸度为pH值2.2;温度升高,吸附量减小,表明吸附是一个放热过程;载银量越大,其苯酚吸附值越小,但影响程度不是太大;如果条件控制得当,用载银竹炭可有效的除去水相的苯酚,去除率可达90%以上。
The adsorption condition and effect of bamboo-charcoal supporting silver(BCSS)for phenol were studied.The results show that the BCSS had high adsorption ability for phenol.The optima adsorption acidity of BCSS for phenol is pH 2.2 in KCl-HCl medium.Adsorption decreased with increases in adsorption temperatures,which means that the adsorption process is an exothermic process.Adsorption decreased with increases in silver content.The adsorption effect can reach as high as 90%in appropriate condition
