Kindly recommend a procedure to determine total kjeldahl-nitrogen Kj-N for leachate.

I am an environmental chemist and have considerable experience with this test.

ASTM methods are copyrighted and so will NOT be found online.

But there perfectly good perfectly available EPA methods that work just as well.

Here is a link that has all the methods you can download:
