초록

농도가 서로 다른 네 가지 과산화수소와 황산 티타늄 수용액의 혼합물의 흡광도를 조사하였는데, 405 nm에서 최대 흡수띠를 보여 주었으며, 과산화수소 농도가 증가함에 따라 흡수띠의 세기가 비례적으로 증가하였다. 이를 이용하여 페놀의 수산화반응에서 농도를 이미 알고 있는 저농도의 과산화수소를 UV-VIS 분광법과 KMnO₄ 적정법으로 정량한 결과 서로 5% 오차 범위내에서 일치하였다. 페놀의 수산화반응에서 생성되는 카테콜, 하이드로퀴논, 파라벤조퀴논과 같은 생성물의 간섭을 받지 않고 잔류 과산화수소(0.5중량% 이하)를 정량할 수 있었다.

Four different concentrations for the mixture of hydrogen peroxide and titanium sulfate solution were prepared and their UV-VIS spectra were observed. The maximun absorption is observed at 405 nm and its intensity increased as the concentration of hydrogen peroxide increased. Based on this result, in the phenol hydroxylation, the determination of hydrogen peroxide by UV-VIS spectrophotometric method is in good agreement with that by KMnO₄ titration method within ±5%. In the presence of catechol, hydroquinone and p-benzoquinone, which were the reaction products of phenol hydroxylation, did not interfere with the determination of hydrogen peroxide by spectrophotometric method.

Keywords:UV-VIS spectroscopy;hydrogen peroxide;determination;phenol;hydroxylation
