WO3/W Nanopores Sensor for Chemical Oxygen Demand (COD) Determination under Visible Light

Abstract

A sensor of a WO3 nanopores electrode combined with a thin layer reactor was proposed to develop a Chemical Oxygen Demand (COD) determination method and solve the problem that the COD values are inaccurately determined by the standard method. The visible spectrum, e.g., 420 nm, could be used as light source in the sensor we developed, which represents a… (More)
