EOSIN CAS 17372-87-1 yog dab tsi?

Eosin Y uas yaj tau hauv dej yog ib qho xim zas uas muaj cov kua qaub uas sib xyaw ua ke hauv cov tshuaj lom neeg uas tawg ua cov anions uas muaj nqi tsis zoo hauv dej thiab khi nrog cov cations uas muaj nqi zoo ntawm cov protein amino pawg kom pleev xim rau hauv cytoplasm. Cov cytoplasm, cov qe ntshav liab, cov leeg, cov ntaub so ntswg sib txuas, cov eosin granules, thiab lwm yam raug pleev xim rau ntau qib xim liab lossis xim liab, tsim kom muaj qhov sib txawv nrog lub nucleus xiav.

Daim Ntawv Thov

Eosin yog ib qho xim zoo rau cytoplasm. Feem ntau siv ua ke nrog lwm cov xim xws li hematoxylin lossis methylene xiav. Siv ua tus neeg sawv cev rau kev zas xim. EOSIN kuj tseem siv ua tus qhia adsorption rau kev txiav txim siab titration ntawm Br -, I -, SCN -, MoO, Ag +, thiab lwm yam. Siv ua tus neeg sawv cev chromogenic rau kev txiav txim siab photometric fluorescence ntawm Ag +, Pb2 +, Mn2 +, Zn2 +, thiab lwm yam.
