Polyacrylamide Worked as Adsorbents for Tetracycline-Polluted Water Treatment

Contamination of tetracycline (TC) in surface and ground water has proven to be a serious environmental concern, due to the extensive usage and the relatively high solubility of TC in water. In the experiments, using polyacrylamide (PAM) worked as adsorbents for tetracycline-polluted water treatment. The prepared PAM was characterized by Fourier transform infrared spectrometry (FT-IR). Operating conditions, such as initial pH value, adsorbents amount and initial concentration of TC were analyzed with the synthetic wastewater in order to optimize the treatment. The experimental results showed that the removal efficiency of TC was 92.9% when the optimum adsorbents amount of 0.15 g, initial pH of 10.0, and the initial concentration of TC of 150 mg/L. The result showed that PAM had a higher adsorptive capacity for TC contaminant. Therefore, it provided a promising adsorbent for environmental purification.
