acid decomposing colorimetric method的用法和样例：
- A tungsten molybdophosphate-casein colorimetric method was used with gallic acid as reference substance.Content of tannin in gallnut and radices sanguisorbae was tested.
- The measurements of the content of cystine using colorimetric method with phosphato-tungstic acid(H2o)3p205(wo3)18 as colrimetric liquid have been carried out.
- Determine its hydrolysate of phosphoric acid using reduction colorimetric method by phosphomolybdic heteroacid and thus calculate the content of fosfosal and moisture absorption rate.
- The determination of acid value of oils by colorimetric method was studied.To avoid the use of expensive surfactant bis (2-ethylhexyl) sulfosuccinate, vortex and centrifugation were used.
