萘甲醛 meaning in English

naphthaldehyde
naphthoic aldehyde

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
第二章利用有机改性的溶胶-凝胶包埋方式,以2 -羟基- 1 -萘甲醛- 8 -氨基喹啉为荧光指示探针,结合正交实验方法探索了几个重要因素,如加水量、醇硅比、催化剂、添加剂等对成膜性的影响,制备了对水中铅离子有较好响应的传感膜,其线性范围为1 . 0 10 - 7 ~ 5 . 0 10 - 5mol / l ,检测限为3 . 6 10 - 8mol / l 。
