EPA Methods 9000 Series

EPA Methods PDF

Welcome to the comprehensive database of EPA methods. These test methods are EPA-approved procedures for measuring the presence and concentration of physical and chemical pollutants; evaluating properties, such as toxic properties, of chemical substances; or measuring the effects of substances under various conditions. The EPA does not release test methods for all chemicals, but only those which it regulates. If you seek other methods besides the EPA, try the general.


Summit Environmental Technologies prides itself in its expansive testing capabilities in a variety of different fields. To find out if Summit conducts this test, contact us at 330-253-8211 today.

EPA METHOD 9016
The sample preparation (Sec. 11.2) is carried out using a microdiffusion cell. The water, wastewater or extract sample is introduced in the outer chamber of the microdiffusion cell and is buffered at pH 6 and placed in the dark for 6 hrs of diffusion. The free cyanide diffuses as HCN gas and is absorbed as CN - into the sodium hydroxide solution located in the center chamber of the microdiffusion cell.
