Granular activated carbon is used to adsorb haloacetic acids from 1L of water. The initial mater concentration of haloacetic acids is 0.9 mg/L. The following data were obtained from an experiment: logg = log k + log C Mass GAC added (g) 0.2 0.5 2.0 5.0 10 20 C, mg/L of haloacetic acids 0.77 0.65 0.32 0.19 0.14 0.09 y = 1.34 (77) +0.018 = 1.158 logg 1=1.34y+0.018 는 logg The Freundlich isotherm analysis by plotting (on y axis) vs. 1/C (on x axis) gives a linear regression line of y = 1.34x + 0.018 with R² of 0.982. Note that q is adsorption density (mass adsorbate/mass adsorbent). What is the required GAC dosage in mg/L to lower the concentration of haloacetic acids to 0.05 mg/L? q = KC we want C=0.05 mg IL
