NGHIÊN CỨU LOẠI BỎ MÀU CỦA PHẨM NHUỘM DB-CC BẰNG PHƯƠNG PHÁP ĐIỆN DI LẮNG ĐỌNG

Tóm tắt

This paper presents the results of dyeing removal study (Dianix® Blue - CC, DB-CC) by
electrophoresis deposition method (EPD) using graphene oxide (GO) as the adsorbent. Physical and
chemical analysis methods such as FT-IR, XRD, UV-Vis and SEM have been used to analyze the
characterization of obtained GO materials. The Zero-charge point (pHpcz) was obtained 2.81.
Parameters such as pH, electrolysis time and potential in EPD experiments, and NaCl concentration
were selected to study. The results found the appropriate conditions are pH 2.8, electrolysis time of 180
s, electrolysis potential of 10 V and NaCl concentration at 1 g / L. Under these conditions the color
removal efficiency has reached 99.92%.
