This thesis consists of four chapters : ( 1 ) a review ; ( 2 ) study on the optical chemical membrane for detection of lead ion by using 2 - hydroxy - 1 - naphthaldehydene - 8 - aminoquinoline as fluorescence indicator ; ( 3 ) study on the optical chemical membrane for detection of lead ion by using meso - ( 4 - methyloxyphenyl ) porphyrin as fluorescence indicator ; ( 4 ) study on the optical chemical membrane for detection of lead ion by using 2 - methene - benzimidazole monoaza - 18 - crown - 6 as fluorescence indicator. in chapter one, the laboratory method for determination of lead ion, the progresses of chemical sensor for detection of lead ion recently and the introduction of the basic theory, relative merits of sol - gel and its application in optical chemical sensor were involved
第二章利用有機改性的溶膠-凝膠包埋方式，以2 -羥基- 1 -萘甲醛- 8 -氨基喹啉為熒光指示探針，結合正交實驗方法探索了幾個重要因素，如加水量、醇硅比、催化劑、添加劑等對成膜性的影響，制備了對水中鉛離子有較好響應的傳感膜，其線性范圍為1 . 0 10 - 7 ~ 5 . 0 10 - 5mol / l ，檢測限為3 . 6 10 - 8mol / l 。 -
The preparation of optically active composite is a promising alternative to obtain a kind of new and competitive sensing membrane for fiber optic sensors, and has attracted the global attention. in this thesis, the modified sol - gel sensing membranes based on fluorescence quenching have been prepared by using tetraethoxysilane ( teos ) and dimthyldimethoxysilane ( dds ) as the main material, formamide as the drying control chemical additive ( dcca ), ru ( phen ) 3cl2 and ru ( bpy ) 3cl2 as the indicator. this kind of membranes is crack - free and has low indicator - leaking rate
