摘要

本文研究了以氧化铝（Al2O3）为活性吸附剂，以抗坏血酸为催化剂，用分光光度法对水溶液中的卡莫辛染料（E122）进行了吸附，并对去除后的染料降解产物进行了分析。结果表明，使用抗坏血酸作为强还原剂可以加速吸附过程。考察了吸附剂用量、染料浓度、接触时间、溶液pH、温度等不同影响因素的影响。卡莫辛染料最大吸附量（qmax）为97 mg g−1。此外，利用紫外可见光谱和红外光谱技术对卡莫辛染料的降解产物进行了吸收测定。该方法可成功应用于废水处理和食品工业。

Spectrophotometric analysis of the degradation products of carmoisine azo dye after removing from aqueous solutions

In this work, the removal of carmoisine dye (E122) from aqueous solutions by adsorption on alumina (Al₂O₃) as an active adsorbent and using ascorbic acid as a catalyst, followed by analysis of the degradation products of the removed dye, has been investigated spectrophotometrically. The obtained data showed that using ascorbic acid as a strong reducing agent can accelerate the adsorption process. The impact of different significant factors, including adsorbent dosage, dye concentration, contact time, pH of the solution, and effect of temperature, was carried out. The maximum adsorption capacity (qmax) of carmoisine dye was found to be 97 mg g⁻¹. In addition, the degradation products of carmoisine dye were investigated by measuring the absorption using UV–visible spectroscopy and FTIR technique. The method can be applied successfully in waste water treatment and food industries.
