Calcium lignosulfonate test Method

How to analyze calcium lignosulfonate

A. 15 lignin content (β- naphthylamine method )
A. 15.1 Equipment
a. Analytical balance ( weighing 200g, a sense of volume 0.1mg);
b. Pipette (10ml);
c. Water bath ;
d. G4 filter bowl .
A. 15.2 Reagents
a. Hydrochloric acid : 0.3N
b. β- naphthylamine hydrochloride solution (C10H7NH2 light HCl): 7.5gβ- naphthylamine were dissolved in hydrochloric acid solution 250ml0.3N , if dissolved , can be slightly heated and filtered to be dissolved after use .
A. 15.3 Test procedure take 1.0g calcium dissolved in 100ml volumetric flask of wood with 0.3N hydrochloric acid to adjust the pH to 3 ( Congo red paper blue ) , plus β- naphthylamine hydrochloride solution 10ml, stir uniform, placed 100 ℃ boiling water bath for an hour, fine yellow precipitate formed gradually , slowly turned orange and brown , and finally the formation of gum. G4 is then filtered using a known weight of the filter cup at 100 ± 2 ℃ oven dried to constant weight , weighed to cool to room temperature in a desiccator .
A. 15.4 The results of the processing of calcium lignosulfonate content is calculated as follows :
Calcium lignosulfonate (%) = a × 0.842 × 1.22 × 100/1.0 = a × 102.72 (A.15)
Where a – precipitation Weight (g);
1.22 – correction factor ; due to precipitation in the β- naphthylamine hydrochloride solution , about 18% lignin sulfonate was not precipitated , still in solution , so to several revisions ; 0 . 842 – β- naphthylamine lignin sulfonate converted into calcium lignosulfonate coefficients.

lignin Details

Lignin is a complex and highly abundant organic polymer found in the cell walls of plants, particularly in woody tissues. It is one of the main components of lignocellulosic biomass, along with cellulose and hemicellulose. Lignin provides structural support to plants and plays a crucial role in the transportation of water, nutrients, and sugars throughout […]
