Abstract

A 17-run Box-Behnken design was used to optimize the synthesis conditions of a monolithic sorbent. The effects of the amount of monomer (mL), crosslink (mL) and porogen (mL) were investigated. The experimental data were fitted to a second-order polynomial equation by the multiple regression analysis and examined using statistical methods. The adjusted coefficient of determination ($R^2$) of the model was 0.9915. The probability value (p < 0.0001) demonstrated a high significance for the regression model. A mean amount of polymer as 2120.15 mg was produced under the following optimum synthesis conditions: the optimized volumes of monomer, crosslink and porogen are 0.30, 1.40, and 1.47 mL, respectively. This was in good agreement with the predicted model value.

Box-Behnken design (BBD) 방법은 일체형 흡착제의 합성조건을 최적화하기 위해 사용되었다. 단량체(monomer)의 양(mL), 가교제(crosslink)의 양(mL), porogen의 양(mL)에 대한 효과를 조사했다. 실험 값은 여러 회귀분석 및 통계적인 방법에 의해 2차 다항 방정식을 얻었다. 이 모델의 결정계수($R^2$)는 0.9915이고 결정계수의 p value는 0.0001보다 작은 값으로 모델이 매우 유의미하다는 것을 나타낸다. RSM 모델에 의해 예측된 최적의 일체형 흡착제 합성조건은 단량체의 양 0.30 mL, 가교제의 양 1.40 mL, porogen의 양 1.47 mL이고 이 조건 아래서 합성된 일체형 흡착제의 양은 2120.15 mg이다. 이 결과는 이 모델이 적절하다는 것을 나타내었다.
