Web3.1.2.Nitrogen removal. Fig. 1 (b) and (c) react the nitrogen removal effect of the three reactors with different Fe 0 dosage. It can be seen that theFe 0 dosage has a significant effect on the nitrogen removal efficiency, and the nitrogen removal effect is better as the Fe 0 dosage increases. As described in Section 3.1.1, the anode microorganisms are … Webpublished a method for the determination of copper in brass (6). We describe two basic methods for determining the quan-tity of copper and zinc in brass. This experiment can easily be carried out during a typical 3-h laboratory period in upper-level undergraduate laboratory and does not require advanced instru-mentation.
