| Abstract: | The typical methods for chlorophyll test were compared between water and wastewater monitoring method （the fourth edition） and ISO 10260：1992（E）. The experiments showed that the test results both had a certain correlation and significant differences. ISO standard had high extraction efficiency and easy operation in the ways of extraction method, extraction solvent and calculation formula. |
