Adsorption of synthetic and real Kinetic Hydrate Inhibitors (KHI) wastewaters on activated carbon: adsorption kinetics, isotherms, and optimized conditions
Type Article
Not Record
The treatment of the KHI wastewater by using activated carbon was investigated. Taguchi method was applied to study the influences of temperature, KHI initial concentration, adsorbent dosage, and pH. The ANOVA results confirmed that initial concentration was the most significant factor and increasing the pH and adsorbent dosage led to an enhancement in the KHI removal. The highest KHI removal was reported at 68.75% and 22.8% at the initial concentrations of 50 and 250 mg/L, for synthetic and real wastewaters, respectively. The results showed that the highest adsorption capacity was 17.75 mg/g.
