The high quantily of proteinfat and the concentration of IronZinc and Selenium ions in the medium is more advantageous to bioconcentration of edible fungi.
When the complex of anhydrous zinc acetate with 1,5-naphthalene diamine was formed, the anhydrous zinc acetate changed from a bidentate ligand to a unidentate ligand.
The feasibility of roasting reduction method to dezinc the Zn bearing BF dust was proved by energy spectrum analysis and differential thermal(DT) and thermo gravimetric(TG) analysis firstly.
Both volumetric method and gravimetric method can be used for determination of Zn in thiofide ZDBC.The gravimetric method is easy to operate but it spents more analysis time.
The Spanish Cross in Bronze was die struck in tombak or bronzed brass and the Silver can be found both in hallmarked 800 grade silver and silver plated brass.
When this method is used for the determination of silica in zincous concentrate, the results are coincident with country standard method, but this method is simpler and more rapid.
