含氮多孔聚合物ARPOP-1修饰碳糊电极用于水中2,4-二氯苯酚的检测

Nitrogen-containing porous polymer ARPOP-1 Modified Carbon Paste Electrode for the Detection of 2,4-dichlorophenol in Water

相关研究表明含氮多孔聚合物ARPOP-1材料对2,4-二氯苯酚(2,4-DCP)有很好的吸附效果。文章以ARPOP-1材料为修饰剂制备了改性碳糊电极传感器,采用方波阳极溶出伏安法(SW-ASV)检测2,4-DCP。结果表明在最佳条件下,2,4-DCP在0.2~20.0μmol L-1浓度范围内与SW-ASV曲线的峰电流呈线性关系(R 2=0.9991),检出限为0.073μmol L-1(S/N=3)。将ARPOP-1材料碳糊电极(ARPOP-1-CPE)的改性传感器测定自来水样及武汉市南湖水样中的2,4-DCP,加标回收率分别为86.35%~102.18%和88.10%~98.94%,证明该方法适用于分析环境水样中的2,4-DCP。

Related research shows that the nitrogen-containing porous polymer ARPOP-1 material has a good adsorption effect on 2,4-dichlorophenol(2,4-DCP).In this paper,a modified carbon paste electrode sensor was prepared using ARPOP-1 as a modifier,and square wave anode stripping voltammetry(SW-ASV)was used to detect 2,4-DCP.The results show that under the best conditions,the concentration of 2,4-DCP in the range of 0.2~20.0μmol L-1 is linear with the peak current of the SW-ASV curve(R 2=0.9991).The exit limit is 0.073μmol L-1(S/N=3).The modified sensor of the electrode(ARPOP-1-CPE)was used to measure 2,4-DCP in the tap water sample and the Nanhu water sample in Wuhan City,Hubei Province.The recovery rates of spiked standards are 86.35%~102.18%and 88.10%~98.94%.The method is suitable for analyzing 2,4-DCP in environmental water samples.
