Abstract:
Microalgae present a viable mechanism for purifying aquatic environments through the absorption of organic pollutants. In this paper, Chlorella protothecoides was cultured in a tetracycline environment, and biochar was added during the cultivation process. Compared with conventionally cultured Chlorella protothecoides, the addition of biochar for cultivation under a tetracycline environment increased the biomass of Chlorella protothecoides by 13.26 %. Moreover, the adsorption of tetracycline by biochar alone was not complete, but when mixed with Chlorella protothecoides, tetracycline was completely removed, which proved the biosorption of Chlorella protothecoides for low concentrations of tetracycline. Finally, the cultured Chlorella protothecoides was used further to prepare electrode materials, and it was found that the specific capacitance of the material reached 233.15F/g at a current density of 1 A/g. In this study, the use of biochar and Chlorella protothecoides to jointly adsorb tetracycline is of great significance for environmental protection and microalgae cultivation.
摘要:
微藻提供了通过吸收有机污染物来净化水生环境的可行机制。在本文中,在四环素环境中培养原壳小球藻,在培养过程中加入生物炭。与常规培养的原壳小球藻相比,在四环素环境下添加生物炭可使原壳小球藻的生物量增加13.26%。此外,生物炭单独对四环素的吸附不完全,但是当与原壳小球藻混合时,四环素被完全去除,这证明了小球藻对低浓度四环素的生物吸附。最后,将培养的原壳小球藻进一步用于制备电极材料,发现在1A/g的电流密度下,材料的比电容达到233.15F/g。在这项研究中,利用生物炭和原壳小球藻共同吸附四环素,对环境保护和微藻培养具有重要意义。
