采用水热法合成污泥基碳量子点。以荧光量子产率为响应值,对水热反应温度、水热反应时间和聚乙二醇添加量进行考察,在单因素试验基础上,结合响应面法优化制备工艺条件。模型拟合回归分析结果表明最佳制备工艺条件为:水热反应时间8.22h,水热反应温度170℃,聚乙二醇添加量0.27g。在此优化条件下进行3组试验,荧光量子产率均值为6.382%,与理论值接近度为98.92%。采用响应面法建立的模型较可靠稳定,可为污泥基碳量子点的制备提供基础理论依据。
Sludge-based carbon quantum dots were synthesized by hydrothermal method.With the fluorescence quantum yield as the response value,the hydrothermal reaction temperature,hydrothermal reaction time and polyethylene glycol (PEG) addition amount were investigated.Based on single-factor experiments,the preparation process conditions were optimized using response surface methodology (RSM).the results of model fitting regression analysis indicated that the optimal preparation conditions were:hydrothermal reaction time of 8.22h,hydrothermal reaction temperature of 170℃,and PEG addition amount of 0.27g.Under these conditions,three sets of experiments were conducted,and the average fluorescence quantum yield was 6.382%,with a closeness to the theoretical value of 98.92%.The model established using RSM was relatively reliable and stable,providing a fundamental theoretical basis for the preparation of sludge-based carbon quantum dots.
