( 2 ) an aminobenthiazole schiff base has been synthesized as a new fluorescence carrier by reacting 2 - aminobenthiazole with p - allyoxybenzoldohyde. the new kind of schiff base can be utilized for preparing an optical sensor, used for determining furazolidone based on the fluorescence quenching. aminobenthiazole schiff base immobilized on a glass plate surface by covalent bonding can circumvent the leakage of the fluorephore from the sensor surface and guarantee a relatively long working lifetime
( 3 )用強熒光基團2 -氨基苯並蒽酮與對烯丙氧基苯甲醛合成了另一種新
的schiff堿類化合物,與甲基丙烯酸羥乙酯、丙烯酰胺、環乙二醇二丙烯酸酯共聚制得光極膜,制備了一種苯並蒽酮schiff堿光化學傳感器,可用於單質

The yield of ac decreases with the increase of koh, activating temperature and activating time while at first the amount of iodine adsorption increases then decreases. the amount of iodine adsorption of ac reached maximum when the ratio of koh to anthracite, activating temperature and activating time are 5, 750 c and 1. 5 hours respectively
隨著堿炭比
的增加,活化溫度
的升高,活化時間
的延長,所得活性炭
的收率減少,
碘吸附值則呈先增大后減小
的變化規律,在堿炭比為5 ,活化溫度為750 ,活化時間為1 . 5h時,活性炭對
碘的吸附出現峰值。
Surface - active agent these play carrier and help function that dissolve in bending over in iodine, complexing ability of them it helps to be very much ideal to dissolve result, these kind of iodine there are quite a few of " existence forms of iodine " that do not possess the sterilization activation but waste of bending over, can leave yellow to dye even burn the skin at skin also at the same time
