Phenols are generated in the wastewater of industrial processes. Phenol is extremely poisonous when entering the human body through the mouth. This study was conducted to determine the parameters of activated charcoal from coconut charcoal produced by Tam Dinh-Phu Yen Company and the ability of coconut charcoal in wastewater containing phenol. | ISSN: 1859-2171 TNU Journal of Science and Technology 200(07): 99 - 105 TREATING PHENOL IN WASTEWATER BY ACTIVATED CHARCOAL Pham Huong Quynh Hanoi University of Industry ABSTRACT Phenols are generated in the wastewater of industrial processes. Phenol is extremely poisonous when entering the human body through the mouth. This study was conducted to determine the parameters of activated charcoal from coconut charcoal produced by Tam Dinh-Phu Yen Company and the ability of coconut charcoal in wastewater containing phenol. The results showed that the specific surface area was 891,7021 m2/g and the surface area of the micropores was 848,3714 m2/g. The moisture was less than 8 percent; the ash was from to and the particle size from to accounted for . The highest emptiness at grain size was , accounting for percent with a small surface area of m2/g. The optimum efficiency of activated charcoal achieved best at pH = 5, the reaction time of 150 minutes, adsorption volume of g; The processing efficiency was from to with the influent of 20-52mg/l. Keywords: Phenol, activated carbon, coconut shell, adsorption material Received: 26/3/2019; Revised: 18/4/2019;Approved: 07/5/2019 NGHIÊN CỨU XỬ LÝ PHENOL BẰNG THAN HOẠT TÍNH SỌ DỪA Phạm Hương Quỳnh Trường Đại học Công nghiệp Hà Nội TÓM TẮT Phenol phát sinh ra trong các dòng thải của quá trình công nghiệp. Phenol được xem là chất cực độc nếu đi vào cơ thể qua đường miệng. Nghiên cứu này thực hiện nhằm xác định các thông số của than hoạt tính sọ dừa được sản xuất bởi công ty Tam đỉnh Phú Yên và khả năng xử lý phenol trong nước của than sọ dừa. Kết quả cho thấy Diện tích bề mặt riêng là 891,7021 m2/g, diện tích bề mặt riêng của lỗ nhỏ (micropores) là 848,3714 m2/g m2/g. Độ ẩm 5mm; 35mm; 2-3mm; ; . Research on phenol treatment Effects of pH on the ability to process phenols Based on the isoelectric point,
