The spent liquor of the sulfite pulping process is dilute and contains other impurities; therefore, lignosulfonates should be separated from the spent liquor for increased commercial value. Because lignosulfonates are…

The sulfite pulping process has many environmental issues, and thus, only a small portion of market pulp (less than 10%, roughly 7 million tons) is produced by the sulfite pulping…

Lignosulfonates or sulfonated lignin are water-soluble anionic polyelectrolyte polymers: they are byproducts from the production of wood pulp using sulfite pulping. Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. The electrophilic carbocations produced…
