The candle soot particles were collected from the inner and outer regions of the candle flame and their dye adsorption capacities were compared. The surface area of inner flame particles (IFP) and outer flame particles (OFP) was recorded as 48 and 88 m 2 g −1 , respectively. The coatings of OFP and IFP were found hydrophobic and hydrophilic, respectively. The adsorptive removal of Methylene blue (MB) (conc. 50 mg l −1 ) was ~40% higher with OFP than that of IFP. Similarly, significantly higher adsorption was recorded during the adsorption of ciprofloxacin and detergent for OFP than that of IFP. The pseudo-second-order model is found most suitable to explain the kinetic data of adsorption.

蜡烛烟灰纳米颗粒的可调吸附活性取决于火焰高度

从蜡烛火焰的内部和外部区域收集蜡烛烟灰颗粒，并比较它们的染料吸附能力。内火焰颗粒（IFP）和外火焰颗粒（OFP）的表面积分别记录为48和88m 2 g -1。发现OFP和IFP的涂层分别是疏水的和亲水的。与IFP相比，OFP对亚甲基蓝（MB）（约50 mg l -1）的吸附去除率高约40％。类似地，在环丙沙星和去污剂对OFP的吸附过程中，记录到的吸附量要比IFP更高。发现伪二级模型最适合于解释吸附的动力学数据。
