Abstract Detail

Abstract

This research focuses on the optimization of process parameters for the chemical activation of camelina meal biochar to enhance its surface area and adsorptive capacity, particularly for the removal of perfluorooctanoate (PFOA), a persistent synthetic compound. Using Central Composite Design (CCD) and Response Surface Methodology (RSM), quadratic models were developed to analyze the effects of key operating conditions, such as temperature (700–900 °C), activation time (60–120 min), and chemical-to-feed ratio (0.5-1.5), on the BET surface area and reaction yield of the biochar. The study found that potassium hydroxide (KOH) assisted activation at 800°C for 120 minutes with a chemical-to-feed ratio of 1.5 produced biochar with the highest specific surface area and a yield. The effectiveness of the activated biochar in adsorbing PFOA was compared to that of other activated carbon samples.
