A Simple Rapid Determination Method of Main Components in Rural Biogas

ZHAO Hong et al (Department of Life Science,Qiannan Normal College for Nationalities,Duyun,Guizhou 558000)  
[Objective] The study aimed to seek for a simple and rapid method of determinating main components in biogas,which was suitable to be applied in rural area.[Method] The fermentation biogas was extracted by injector with volume of 1 ml and CO2 in biogas was absorbed by KOH or NaOH solution,so the content of CO2 in biogas was determined and compared with that determined by GC,then the content of CH4 in biogas was calculated out.[Result] The content of CO2 in biogas could be determined more accurately by NaOH and KOH solutions and the difference was not significant(P0.05).The content of CO2 determined by this method had extremely significant correlation with that determined by GC(P0.01).The variation coefficient of CO2 content in biogas determined by KOH solution was 1.19%,which was in the scope allowed by GC.[Conclusion] The determination method established in the study was simple and rapid and had higher accuracy in determining the content of CO2 in biogas,so it was suitable to be applied in the operation management of rural biogas digester at present.
