有机抽提对泥炭中的木栓质体荧光光谱特性的影响

INFLUENCE OF EXTRACTION ON FLUORESCENCE OF THE SUBRENITE IN THE PEAT

对泥炭中的木栓质体及泥炭有机抽提残渣中的木栓质体进行了荧光（光谱）对比研究，研究发现有机抽提对泥炭中的木栓质体的荧光（光谱）性影响很大。有机抽提前泥炭中的木栓质体发鲜艳的黄绿至绿色荧光：λｍａｘ＝４７０～５２０ｎｍ；Ｑ６５０５００＝０．１０～０．５４。有机抽提后泥炭中的木栓质体则发暗黄色至橙黄色荧光：λｍａｘ＝６０５～６６０ｎｍ，Ｑ６５０５００＝１．８５～４．０９。

Comparative study on the subrenite in the peat and extracted remain has been made.The study reveals that extraction has considerable influence on the fluorescence of the subrenite. Before extracted,the subrenite in the peat gives out violently fresh yellowish green to green fluorescent light,and the λ max  ranges from 470 to 520nm and the Q 650500  from 0 10 to 0 65,but after extracted,the subrenite in the extrated remain gives out weakly dark yellow to orange yellow fluorescent light and the λ max  ranges from 605 to 660nm and the Q 650500  from 1 85 to 4 09.The extraction has made the fluorescent intensity of the subrenite weak.
