Abstract

Background

Copper (Cu²⁺) and antibiotics are common and co-existing pollutants in wastewater from livestock and poultry farms.

Methods

Magnetic porous carbon (Fe_XZn@BC) with different iron contents was prepared by one-step using zinc chloride and ferric chloride as modifiers. Tetracycline (TC) and Cu²⁺ as target pollutants were used to investigate the adsorption properties of Fe_XZn@BC. Additionlly, the degradation performances of Fe_XZn@BC activating peroxymonosulfate (PMS) and iodide (IO₄⁻) on TC degradation were further investigated.

Significant Findings

The order of the adsorption capacities of the adsorbents for TC was (mmol·g⁻¹): Fe₂Zn@BC (1.39) > Fe₅Zn@BC (1.09) > Fe₁₀Zn@BC (1.03) > BC (0.03), and for Cu²⁺ was (mmol·g⁻¹): Fe₂Zn@BC (1.93) > Zn@BC (1.39) > Fe₅Zn@BC (1.29) > Fe₁₀Zn@BC (1.00) > BC (0.28). The Fe_XZn@BC also could catalyze PMS for TC degradation, and the removal of TC by PMS could be strengthened in the presence of Cu²⁺. Dynamic experiments on the removal of TC in water using Fe₂Zn@BC were conducted, and the effects of PMS and Cu²⁺ on the dynamic experiments of TC removal were investigated. This study provides a new perspective on the co-removal of antibiotics and heavy metals Cu²⁺.
