Extractives of Organics from Eucalyptus APMP Effluents and Its Inhibition Effect on Growth of Microcystis aeruginosa
摘要
Abstract
Eucalyptus APMP effluents were extractedby ethyl acetate (EA) and methyl tertiary butyl ether (MTBE) and the extractives were anaylyzes by GC-MS.The results showed that the yield of EA extractive was 204 mg/L with 44 kinds of organic compounds, and the yield of MTBE extractive was 132 mg/L with 49 kinds of organic compounds.The extractives were composed by acids, alcohols and esters,in which acids were the main compounds accounting for about 76% (extracted by EA) and 80% (extracted by MTBE), respectively.Inhibition effect of EA extractives on the growth of Microcystis aeruginosa was investigated.The results showed that the extractives from APMP effluents inhibited the growth of M.aeruginosa with different effect in different concentrations.The inhibition effect was not remarkable at low extractive concentrations, and the inhibition effect was significant when the concentrations were over 50 and 100 mg/L, with the inhibition rates of 24.8% and 77.2%, respectively.The inhibition effect would be further investigated through the absorbent under 446 nm.关键词
