미국 EPA가 주요 유기오염물질로 정한 페놀류들에 대하여 역상 액체 크로마토그래피에서 혼합용액을 등용매 용리법으로 완전히 분리할 수 있는 최적 분리조건과 머무름 거동을 조사하였다. 이때 정지상은 μ-Bondapak C18 컬럼을, 이동상은 메탄올-물, 아세토니트릴-물, THF-물을 사용하였다. Statistical simplex system의 삼

The optimum condition for the separation of priority pollutant phenols using isocratic elution has been determined. The elution behavior of eleven phenols has been also studied to interpret the retention. The reversed phase liquid chromatographic methods were performed on a μ-Bondapak C18 column with methanol-water, acetonitrile-water, and THF water mixtures as mobile phases. The COF method, where Snyder's solvent triangle concept was combined with a mixture-design statistical technique, was used to optimize the strength and selectivity of solvents for the separation of phenols. The optimum solvent composition, which gives a complete separation of eleven phenols, was found to be MeOH:ACN:H2O = 7:40:53. The plots of ln k' vs. -ΔHo and ∑π of phenols showed relatively good linearities. Effect of van der Waals volume, pi-energy and hydrogen bonding on the retention of phenols were investigated. The following equation with the correlation coefficient of 0.9927 for ACN-water solvent system was obtained; log k' = 2.515 × 10-2 VWV - 1.301 × 10-1 E - 3.674 × 10-1.
