The purpose of this research is to conduct a complex study on its physical-chemical and pharmacological properties. Samples of cotton hydrolyzed lignin based enterosorbent Zerotox were investigated, wood hydrolyzed lignin based enterosorbent Polifepan （Russia） was used as a comparison drug. The technology of new medical enterosorbent Zerotox, based on cotton hydrolyzed lignin, has been developed with its physical-chemical and pharmacological characteristics being researched. Comparative research on adsorbing capacity of sorbent Zerotox （80 mg/g） and its analogue--Polipefan （55 mg/g）, which is obtained from wood hydrolyzed lignin, has displayed advantages of the new sorbent. IR-spectroscopy research on lignin sorbent Zerotox has shown presence of oxygen-containing functional groups which determine its high absorbing capacity due to its chemisorption.
