摘要
利用玻璃真空系统 ,采用原位红外动态方法 ,分别研究了 30℃ ,40℃ ,5 0℃活性炭A,B,C,D吸附 CS2 的行为 ,红外谱图显示 4种活性炭吸附 CS2 主要是物理吸附 ,但浸渍了有机胺的改性活性炭 C和活性炭 D上发现 ,有活性组分中的 N原子与 CS2 和碳链共同作用所形成的可逆的弱的化学吸收峰 .与空白活性炭 A相比较 ,样品 C和 D的 CS2 吸收峰面积明显增大 ,而浸渍KOH的样品 B,其 CS2 吸收峰面积没有增大 .
The adsorptions of CS 2 were investigated at 30 ℃,40 ℃ and 50 ℃ on activated carbon A,B,C and D by FTIR equipped with a set of glass-vacuum apparants. The results showed that CS 2 adsorption was mainly physical adsorption. Weak reversible chemical adsorption peak were found in infrared spectra of the activated carbon C and D which were impregrated with organic amine. Compared with blank activated carbon A, the CS 2 adsorption peak areas of type C and D increased obviously. No effect was found on type B impregrated with KOH.
