摘要:
开发一种新的二氧化硅石墨烯电极的应用，通过恒电位电解检测化学需氧量，考察氧化电位、电解质浓度和溶液pH等基本参数对二氧化硅石墨烯电极响应电量的影响，获得了最佳操作条件。本方法检测时间为15 min、样品用量10 mL。检测范围为5-60000 mg/L，检测限为4.37 mg/L，稳定性强。将该电极应用于不同实际废水样品的测定，所得结果与重铬酸钾法一致。
Abstract:
A new application of silicon dioxide graphene electrode was developed to detect chemical oxygen demand by potentiostatic electrolysis. The effects of basic parameters such as oxidation potential, electrolyte concentration, and solution pH on the response capacity of the silica graphene electrode were investigated, and the optimal operating conditions were obtained. The detection time of this method is 15min, and the amount of sample is 10mL. The detection concentration range is 5-60000mg / L, the detection limit is 4.37mg / L, and the stability is strong. This electrode was applied to the determination of different actual wastewater samples, and the results obtained were consistent with the potassium dichromate method.
