초록

KS, JIS, ASTM 및 OECD의 계면활성제 생분해 공정시험법인 진탕배양법, 반연속식활성오니법, 연속식활성오니법을 이용해 APG의 생분해성을 조사하였다. Foam loss로 측정한 APG의 일차생분해도는 모든 시험법에서 100%인 것으로 나타나, APG는 하수처리장과 표층수의 조건에서 쉽게 분해됨을 확인할 수 있었다. 또한 OECD의 화확물질 생분해 평가법인 closed bottle test법으로 측정한 APG의 최종생분해도는 75% BOD₂₈/COD로, OECD에서 제시한 ready biodegradability limit인 60%를 초과하여, APG는 자연계에서 쉽게 분해되는 "readily biodegradable"한 물질인 것으로 확인되었다.

The biodegradability of alkylpolyglucosides(APGs) was determined by shake culture tests, semicontinuous activated sludge test, and continuous activated sludge test mandated for testing the biodegradability of surfactants in OECD, ASTM, JIS and KS. APGs showed 100% foam loss in all tests. This means that APGs are degraded well not only in sewage treatment plant but in surface water conditions. In closed bottle best for determinating the ultimate biodegradability, APGs exceeded the ready biodegradability limit (60%) of OECD with 75% BOD₂₈/COD. APGs may therefore be considered as readily biodegradable under actual environmental conditions.
