【摘要】：以农业废弃物玉米苞叶为原料,用氯氧化锆对其进行改性,用于去除水体中的四环素。采用SEM、FTIR对改性前后的玉米苞叶进行了表征,并研究了溶液初始pH、温度等因素对四环素吸附的影响。结果表明:改性过程使玉米苞叶表面结构发生变化,显著提高了其对四环素的吸附量。在30℃,四环素溶液初始pH=5的条件下,吸附量为54.1 mg/g。在293~313 K的温度范围内,吸附量随温度的升高而升高,等温吸附曲线符合Freundlich模型;吸附过程符合伪二级动力学模型。

The effects of the initial pH, temperature on the adsorption of tetracycline were studied by means of SEM,FTIR. The results showed that the surface structure of maize bracts was changed and the adsorption of tetracycline was significantly increased during the modification. At 30 鈩，
