Gas emissions (CO2, CH4, N2O) were studied in situ from the treatment bed of a constructed
wetland with horizontal subsurface flow planted with Phragmites australis. The system …

Recent advances in oxygen demand research have expanded the number of options
available for testing. The purpose of this technical bluebook is to 1) provide background …

Protection of water environments is an important part of overall environmental protection;
hence, many people devote their efforts to monitoring and improving water quality. In this …

This study proposes a modification to the standard method for the determination of the
chemical oxygen demand of samples with a salinity up to 40g NaCl/L and low organic …

The construction and performance evaluation of a novel Chemical Oxygen Demand (COD)
sensor is described. The sensor measures, using an oxygen electrode, a decrease of …

1. Nutrient and chlorophyll a levels, and bacterial numbers of 84 glacial lakes in the Tatra
Mountains (Slovakia and Poland, Central Europe) were determined to assess the impact of …

This work reports on the fabrication and comparative analytical assessment of
electrochemical sensors applied to the rapid analysis of chemical oxygen demand (COD) in …

This work focuses on the experimental studies of a photoelectrocatalytic method for COD
determination in a thin-cell reactor based on a highly effective TiO2 nanotube array …

Indium borate has been prepared by a sol–gel method. The structure, morphology, and
photophysics of the resultant photocatalysts have been studied via the techniques of X-ray …

An electrochemical detection system with an F-PbO2 modified electrode for flow injection
analysis to determine chemical oxygen demand (COD) was proposed and experimentally …
