| Tartalmi kivonat: | Search for efficient, inexpensive and environmental friendly sorption material for application in the sugar industry was always been in the research focus. Bentonite as natural material with great affinity for binding inorganic and organic compounds could fulfill the previous requirements. This study investigates application of two different sodium-calcium bentonites (Claris p30 and Claris p50) as adsorbents in the purification of sugar beet molasses. BoxBehnken experimental design was employed and the effect of 3 independent variables pH (3, 5, 7), molasses dry substance (30, 40, 50°Bx) and bentonite suspension concentration (9, 15, 21 g/L) on the sugar beet molasses color and turbidity reduction were studied. Positive results regarding color reduction (22% with Claris p30 and 48% with Claris p50) and turbidity reduction (90% with Claris p30 and 99% with Claris p50) of sugar beet molasses were obtained upon treatment with corresponding bentonites indicating their applicability as environmental friendly adsorbents of non-sugars from the sugar industry. |
