| description | Tabii tapak aktif dalam aluminosilikat untuk penjerapan
B-karotena telah diperiksakan. Zeolit bertukaran kation mempunyai berbagai darjat pertukaran NH4+, Mg2+, Ca2+, Fe3+ dan Cu 2+ telah disediakan. Kehabluran sampel-sampel itu aelepas diaktifkan pada 450 °C telah Hiperiksakan oleh difrakse sinar X dart luaa permukaan ditentukan dengan penjerapan N2 (BET). Keasidan permukaan sampel ini juga ditentukan oleh pentitratan tak-berair dengan menggunakan
penunjuk trifenilmetanol.
The nature of active sites in aluminosilicates for the adsorption of B-carotene was investigated. Cation exchanged zeolites with varying + 2+ 2+ 3+ 2+ extent of exchange of NH4+, Mg2+, Ca2+, Fe3+ and Cu2+ were prepared. The crystallinity of these samples activated at 450°C were checked by x-ray diffraction and the surface areas were determined by N2 adsorption (BET). The surface acidities of the samples were also determined by.
nonaqueous titration using triphenylmethanol indicator.
