Based on the theory that a droplet will absorb some spectrum when the spectrum goes into and out of a droplet,the change of propanol/acetone droplets initially from about 2 to 3 mm in diameter was measured.

Effective calcium oxide in lime can be combined with sucrose to create higher-solubility calcium sucrose while calcium carbonate in lime and other calcium salts don t act with sucrose,by which to separate it,then the EGTA titrimetric method was used to determine effective calcium oxide content.

Determination of total iron in cold-compacted bulk for converter steelmaking with EDTA titration;

Adjustment and Control of Acidity by EDTA titration,;

Determination of magnesium during producing electrolytic manganese by manganese dioxide precipitation-EDTA titration;

However there are many restrictions for applying EDTA titration method in engineering practice.

In this paper the mechanism of the EDTA titration method is expatiated and t.

It illustrates the concept of EDTA titration method,introduces in detail the methods of EDTA titration method quickly measuring cement stability and content and points out that titrated results revised by revising curve ages of which has been considered can assure accuracy of made-up testing results better.
