Sorbent Properties of Orange Peel-Based Biochar for Different Pollutants in Water

Efficient and reasonable utilization of waste biomass resources can not only avoid serious material resources, but also solve the problem environmental pollution. Therefore, development efficient environmentally friendly carbonization technology has important practical significance. Here, activated carbon from orange peel (OAC) is prepared by potassium hydroxide (KOH) activation combined with high-temperature carbonization. The adsorption effects OAC on three different pollutant aqueous solutions, methylene blue (MB), tetracycline (TC), fluorescein sodium (NaFL), are examined. absorbent excellent capacity for MB, TC, NaFL pollutants 10 mg L−1, rates 99.17%, 73.5%, 94.24%, respectively. This study provides a new idea turning into treasure eliminating hidden danger
