摘要
The influence of microwave irradiation on chromium sulphate solution was studied to provide a foundation for effectively utilizing microwave in the tanning process. The chromium sulphate solution was heated by microwave with a sample heated by water bath at the same condition as a control. During the process, the pH, conductivity, dielectric constant and UV-Visible absorption spectrum of chromium sulphate were measured to study the influence of different heating methods on chromium complexes hydrolysis and on the olation process. The results demonstrated that both microwave and water bath methods could lead to the chromium sulphate pH dropping, conductivity increasing, UV Visible characteristic absorption peak shifting to violet, R value enlarging and dielectric Constant increasing. However, the microwave irradiation had much more obvious effects on these changes than the water bath, indicating that microwave irradiation could promote chromium sulphate hydrolysis and olation further. This research proved the both uniform thermal effect and non-thermal effect in the chromium sulphate solution under microwave irradiation, and that these effects could benefit the chrome tanning process in the future.
