คำอธิบาย

General description

Lignin, alkali is a complex, three dimensional polymer that is also known as kraft lignin that has undergone hydrolytic degradation. It is one of the major components of lignocellulosic materials. Lignin is a major product for second generation bioethanol production and is an impurity in the separation of cellulose from wood.

Application

Lignin, alkali can be used as a surface treatment agent for composites of natural fibers with petroleum based resins. It can be used as a biosorbent for potential applications in removing toxic metal ions from wastewater.
