1) On the basis of the determination of ammoniacal nitrogen in compound fertilizers by the Type AA3 continuous flow analyzer a study is made to compare it with the national standard method.

2) Among all the leachingtechnologies investigated , acid leaching, ammoniacal leaching and bacterial leaching are emphatically introduced.

3) Objective To observe the relation between higher ammoniacal gas and gold hamster's pneumonia in the feeding room.

4) Ammoniacal synthesis procedure has some dangerous characteristics, for example: temperature, press , flammability,(http:///ammoniacal.html) explosive and so on.

5) Synthetic samples were prepared and studied to simulate the phase changes of iron—cobalt compounds in the reduction roasting—ammoniacal leaching processing of oxidized ore.

6) Determination of ammoniacal nitrogen content in the presence of other substances which release ammonia when treated with sodium hydroxide. Titrimetric method.

7) Test results showed that use of ammoniacal solution pretreatment can effectively remove copper, and thus alleviating negative effect of copper on leaching of gold.

8) The traditional method to deal with the coke plant wastewater is a means using by the active dreggy mud, which has less effect on the hard-degraded substance and ammoniacal nitrogen.

9) A study for leaching of a low grade and difficult to separate copper ore was performed by using ammoniacal pressure leaching method.

10) Biomembrane is one of the important processes for degrad ating COD, phenol and ammoniacal nitrogen in wastewater treatment of petrochemical industry.

11) This paper studies the process of the extraction of gold by ammoniacal thiosulfate leaching from the roasted copperbearing sulphureous gold concentrate.

12) Skim serum is an industrial effluent from rubber factories. It is of higher BOD and contains about 1% protein and 0.05-0.3% ammoniacal nitrogen, etc.

13) The key stage of the process controlling was aerobic reactor (O1), in which put the immobilized predominance bacterium could control the last effluent Ammoniacal—nitrogen.

14) A thermodynamic analysis of cementation of Ag with Cu in ammoniacal solution has been carried out. The calculated results indicated that this cementation reaction is possible thermodynamically.

15) The characteristic indexes of Daqu aroma - producing capability include ammoniacal nitrogen and the specific consumption of amylum.
