Active sites for adsorption of B-carotene

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...
