“…Increasing the temperature from 295 to 304 K gave rise to almost four times increase in the effective diffusivity. Our findings are in agreement with those of Seikova and Simeonov (2003), where D e values were reported to be 2.52 × 10 -10 -4.79 × 10 -10 m² s −1 during the extraction of alkaloids from Atropa belladonna (Seikova & Simeonov, 2003). Regarding mass transfer coefficient, increasing temperature from 295 to 304 K resulted in more than 4 times increase in the K T values (from 0.2335 to 0.9720 m s −1 ).…”

“…Figura 10 -Esquema de transferência de massa via difusão em sólido poroso não uniforme. GEANKOPLIS, 1980;SIMEONOV, 2003;TREYBAL, 1981). A difusividade efetiva é um parâmetro de suma importância no estudo da lixiviação, principalmente no que diz respeito a sua modelagem e também ao projeto do equipamento, considerando-se que é comum que a etapa limitante da operação seja a transferência via mecanismo de difusão.…”
