摘要

The present research involves the synthesis, characterization, and optimization of a remarkably effective Mg–Al Layer double oxide (LDO) cross linked to chitosan (LDO@CS) as novel sorbent, which was synthesized by co-precipitation technique. The removal of tetracycline (TC) was investigated through an effective and eco-friendly sorption process. The results showed the surface of LDO@CS was rougher, irregular and have higher function groups than LDO and CS. Effect of variable factors on sorbent process, including pH, initial concentration, dose and type of sorbent were examined via Response Surface Methodology (RSM) and Taguchi. These two methods are more economical than traditional method by reducing the number of experimental steps and can also be used for experimental design and interaction of variables. Both Taguchi and RSM method gave almost the same response, with the interpretation that based results of mean percentage error (PE%) the accuracy of RSM was more than Taguchi. The R2 value of model obtained from RSM and Taguchi were 0.79 and 0.53, respectively demonstrated RSM was more sufficient. RSM results demonstrated LDO@CS effectively improved removal of TC with optimal adsorption capacity of 199 mg g−1 at pH = 5.23, dose of 0.218 g L−1, and initial TC concentration of 92.55 mg L–1. High effectiveness, Rapid synthesis, economical and eco-friendly of LDO@CS are one of desirable features of this sorbent. It is concluded that in order to improve the efficiency of sorbent systems much more emphasis must be placed on the optimization of TC conditions using efficient optimization models especially RSM.
