Abstract
기-액 계면, 흡착 조작에서 계면과 액 본체 사이의 흡착열을 구하기 위하여 이상용액과 단분자 흡착의 가정하에서, 포말간의 동반액체를 고려하여, 회분조작에 대한 물질수지로부터 흡착열을 구하는 관계식을 도출하였다.
Sodium lauryl sulfate와 sodium dodecylbenzene sulfonate에 대하여 4×10-3 mol/l 이하에서 이 관계식과 회분흡착 실험자료에서 흡착열을 구하였다.
그 결과는 표면과잉 농도에 의하여 계산된 흡착열과 일치하였다.
이들 각 용액은 4×10-3 mol/l이하의 농도에서, 기-액 계면 흡착모형은 단분자 흡착으로 생각되었다.

In order to investigate the heat of adsorption at the interface between surface phase and bulk liquid of sodium lauryl sulfate and sodium dodecylbenzene sulfonate in the bubble-foam adsorptive separation, two equations were derived from the batch analysis around the overhead flow of the batch bubble adsorptive separation under the assumption of ideal solution and monolayer.
Using the experimental data obtained from the batch operation below the concentration of 4 × 10-3 mol/l sodium lauryl sulfate and sodium dodecylbenzene sulfonate respectively, the heat of adsorption were calculated by two equations.
The heat of adsorption calculated by the equation, which was derived considering the bulk liquid accompanied by the bubbles, was constant within the range of experimental concentration and was coincided with the value calculated by surface excess.
