Cellulose Chelating agents

Sequential extraction was performed as described by Redgwell and Selvendran [1], WUS was sequentially extracted with chelating agent (ChSS), dilute alkali (DASS), 1 M alkali (1 MASS) and 4 M alkali (4 MASS) and a cellulose-rich residue (RES) remained. 

Classically, wall polysaccharides have been separated into three fractions the pectic polysaccharides, which are extracted by hot water, ammonium oxalate solution, weak acids, or chelating agents the hemi-celluloses, which can be extracted by relatively strong alkali and the residue remaining, which is composed mainly of cellulose. Although these extraction techniques suffer from incomplete and overlapping extraction of the polymers, they are still widely used. 

Use Solvent for cellulose acetate, intermediate, chelating agent for metals, paint driers, lubricant additives, pesticides. 

Mineral Constituents. Cellulose fibers usually contain about 1% ash. The mineral elements contained in the ash include all those essential for the growth and development of cellulolytic microorganisms. This fact has led to speculations and certain experimental treatments by Baechler (4) and others showing that chelating agents applied to cotton or wood can so effectively bind these essential mineral elements that the growth of cellulolytic microorganisms is prevented.
