The 2-Minute Rule for chemical oxygen demand test

Here are a few standardized strategies for measuring COD, but the most typical may be the dichromate reactor digestion technique which will involve the reaction of sample with potassium dichromate in a very sulfuric acid Alternative.

By acquiring a mercury-totally free test kit, we created a colorimetric test process which can be useful for quick analysis of COD degrees without stressing about mercury contamination or jogging afoul of regulatory prerequisites.

The existence of a enough concentration of dissolved oxygen is significant to protecting the aquatic everyday living and aesthetic high quality of streams and lakes. Determining how natural and organic make any difference impacts the focus of dissolved oxygen (DO) in the stream or lake is integral to water- high-quality management.

The merged capabilities of those devices and reagents will aid your regulatory compliance method.
