Effective removal of heavy metals from aqueous solutions by orange peel xanthate, Trans. |
After the alkali cellulose has aged, carbon disulfide is added to form cellulose xanthate, which is dissolved in sodium hydroxide. |
A composition which comprises a mixture of a tetrabenzylthiuram sulphide and one or both of a dihydrocarbyl xanthogen polysulphide and a xanthate selected from metal hydrocarbylxanthates and dihydrocarbylxanthates. |
Cellulose xanthate has numerous applications in various industries, among which mention can be made of its application in floating metals in the extracted mineral rocks. |
Xanthate anions and protonated xanthic acid contain a free thiol moiety and are highly reductive. |
The alkali cellulose is next converted to cellulose xanthate crumb by reaction with carbon disulfide. |
