摘要:
A sample of lignite from Elbistan was oxidized by nitric acid in two stages, using relatively dilute acid in the first stage and concentrated acid in the second stage, and then the oxidized product was ammoniated so that a coal-based fertilizer could be produced. The experiments of all the stages were designed by a 1/2 X full factorial design. It was observed that base exchange capacity and nitrogen content of coal-based fertilizers produced in this work were as good as or better than those obtained by other investigators.
