摘要:
探索了一种用于原位监测地下水中突发性苯系物污染的单室生物电化学（BEC）传感器系统，该传感器采用转刷式阳极及漂浮空气阴极，根据有机物浓度与系统最大输出电压之间的线性关系对有机物进行定量分析。结果显示，在一定浓度范围内，苯或甲苯与系统最大输出电压均能呈现良好的正向线性关系（苯：6~50 mg/L，R2=0.993 7；甲苯：2.3~50 mg/L，R2=0.990 7），线性范围内的响应时间为2.7~6.5 h。在恒定浓度和波动浓度有机污染场景下，系统监测结果的相对标准偏差小于15%，与真实值的相对误差在10%以内，表明BEC传感器在地下水突发性苯系物污染监测方面具有一定的潜力。
Abstract:
A single-chamber bioelectrochemical (BEC) sensor system was developed for the in-situ monitoring of sudden benzene compounds contamination in groundwater. This system utilized a rotary brush anode and a floating air cathode to quantitatively assess organic matter concentrations, based on the linear correlation between organic matter concentration and the system’s maximum output voltage. Within a specific concentration range, both the concentrations of benzene and toluene exhibited a strong positive linear correlation with the system’s maximum output voltage (benzene: 6-50 mg/L, R2=0.993 7; toluene:2.3-50 mg/L, R2=0.990 7). The response time within this linear range was 2.7 h to 6.5 h. Under both constant and fluctuating concentration of organic pollution, the relative standard deviation of the system’s monitoring results was less than 15%, and the relative error compared to the true value remained within 10%. This demonstrates that the BEC sensor holds promising potential for monitoring sudden benzene compounds pollution events in groundwater.
