This study focuses on the evaluation of toxicity changes at water treatment by bioassays, which are expected to give much more relable information regarding the effects on human health. Seven pesticides were added to the groundwater to prepare a model pesticide contaminated water. The changes in pesticide concentrations at ozonation and activated carbon treatments do not correspond to the changes in mutagenicity and cytotoxicity. Especially, the concentration of Dichlorvos and Thiobencarb were degraded with ozonation time increasing. However, the treated water showed different mutagenicity and mutagenicity and cytotoxicity, caused by the different reaction byproduct.

The adsorption equilibrium of phenol derivatives in aqueous solution onto activated carbon was carried out in a batch system. The saturated adsorption amounts of phenols onto activated carbon was in the following order, TCP > ONP > MNP > PNP > DCP > OCP > PCP > PH HOMO and LUMO energy of adsorbates were determined by molecular orbital theory and adsorption equilibria could be expressed by the Freundlich equation. The isotherm constants k and n are listed in Table 3. HOMO and LUMO energy could be correlated against Freundlich constants by the following empirical equations respectively, n = 0.45[HOM] + 1.65 (r=0.925) k = -0.75[LUMO] +8.2 (r=0.913) The saturated adsorption amounts was increased, according as the HOMO energy increased at same system.

활성탄에 의한 수용액 중의 헤테로고리화합물의 흡착은 Freundlich형 등온식으로 설명할 수 있으며, Freundlich 상수의 곱 [k·n]은 끓는점(T_b)에 대하여 직선적으로 증가하였다. 포화흡착량(q_s)은 하메트상수(σ), 유발상수(σ^*) 및 극성상수(F)에 대하여 직선적으로 감소하였으며, 흡착속도는 표면확산이 지배적이었다. 표면확산계수(D_s)와 평형흡착량(q_e)과의 관계는 D_s=D_(so)·exp[a·q_e]로 표시할 수 있었으며, 관능기 종류 및 위치에 따라 속도인자 D_(so)와 a를 각각 구하여 Table 5에 제시하였다. The isotherm of heterocyclic compound in aqueous solution onto activated carbon was correlated with Freundlich type equation, and Freundlich constant product [k·n] appeared linear relationship with boiling point(T_b). Saturated adsorbed amount(q_s) decreased with hammett constant(σ), inductive constant (σ^*) and polar constant(F). Surface diffusion was considered to be dominant. Relationship between surface diffusivity(D_s) and equilibrium adsorbed amount(q_e) was D_s=D_(so)·exp[a·q_e]. Kinetic parameter D_(so) and a was shown Table 5 for kind and position of functional groups.

Liquid phase adsorption of organic compounds solution on the activated carbon fiber was measured by chromatographic method in a packed column. Adsorption equilibrium constant Ka of dextrose solution was found to be 72.5㎠/g on ACF without bacteria growth, while in the bacterial ACF packed column Ka was 87.9㎠/g. It is suggested that for biological ACF there is a large contribution of bacterial activity to the adsorption equilibrium constant. Axial dispersion coefficient Ez was determined to be in proportional to flow rate and Pe=dpu/Ez independent of existence of bacteria.

Adsorption equilibrium and kinetics of Caffeine and Nicotine from aqueous solution on activated carbon were determined experimentally in a batch system. Then, the equilibrium data were expressed by the Freundlich type and the equilibrium constants were obtained. Diffusion coefficient were determined by comparing experimental decay curve with theoretical ones. Surface diffusion was consided to be dominant and the value of diffusion coefficient were depent of the amount adsorbed and the equilibrium concentration. Domestic activated carbon has nearly same amount of adsorption as imported activated carbon made by CALGON carbon Corp.

We studied on the sublimatographic characters of sulfur as follows; 1) Vacuum condensing point of sulfur at different heating temperature and vacuum degree is obtained. 2) Amount of sublimation of sulfur is determined quantitatively by the sublimatography. 3) The vapor pressure, molar velocity of sublimation and mass transfer coefficient of sulfur are calculated by experimental data as follows; P_h/P_s=γ (γ=1.03) P_s^n=k G (n=0.977) (γP_s)^n'=k'G (n'=1.0) k_(gav)=1.3985 × 10^-2
