1, Acid dye colorimetry was used for the determination of cyclovirobuxine D.

2, As for dyeing , weak acid dye and reactive dye should be selected and fullincolor fastness.

3, An acid dye colorimetry method was developed for the determination of cyclovirobuxine D and its tablets.

4, This method was an improvement on acid dye direct titration.

5, Method: Acid base titration and colorimetric method of acid dye were used.

6, The levelness and penetration of acid dye were the best and the color fastness to washing could increase by 1/2 or 1 grade by fixation treatment; 3.

7, Total alkaloids of aconite was determined by acid dye colorimetry.

8, The properties of modified wool, wool and cashmere, as well as the dyeing rate of weak acid dye,(http:///acid dye.html) neutral dye reactive dye to these fabrics were tested.

9, The flocculation performance of the salt applied to the wastewater with high concentration and high colority from J acid dye production has been studied, and its...

10, METHODS: The contents of total alkaloids, diester diterpenoid alkaloids and polysaccharides were measured by acid dye colorimetry, HPLC and sulphuric acid-anthrone colorimetric method respectively.

11, The main results were as following:The content of the total alkaloids in Sophora alopecuroides L is analyzed by the acid dye colorimetry method and the result is 8.21%.

12, Discusses dyeing behaviour of anionic dyes such as direct dye, reactive dye, acid dye and cationic dye on crease-resist finished cotton fabrics with CA.

13, Maily used to dye for vat dye, reactive dye and acid dye. It can work as dispersant for acid staining pad and pigment pad dyeing, auxiliary for reducing dye powder and slurry.

14, OBJECTIVE:To establish a method for content determination of matrine in it's liposomes by acid dye colorime_ try.

15, After that, the finished fabrics were dyed with weak acid dye.

16, It has characteristic functional groups of both wool and polyacrylonitrile, so it can be dyed by acid dye or cationic dye.

17, The direct dye was the most suitable dye in this system, the large molecule acid dye was superior to the small one. The reactive dye can be applied in the sy...

18, Quaternized reactive formaldehyde-free color-fixing agent HET was synthesized, and its color fixation effect was tested for wool dyed with acid dye red G.

19, It is applicable to fixation of the fabric dyed with the anionic dye, such as the direct dye, the acid dye, etc.

20, Objective:The content of cyclovirobuxinum D in Ningxin dropping pills was determined by acid dye colorimetric (ADC).
