“…The diffusional rates within each pore distribution could be significantly different. For example, in the larger pores created by the binding material diffusion rates might be larger than the diffusional rates within the smaller pores contained It has been observed by Ma et al (1996) and Robinson et al (1994) that for ion exchange materials with high capacities and affinities for certain ions (who generally have non-linear isotherms), parallel pore and surface diffusion is occurring. Based on equilibrium ion-exchange, Ma et.…”

“…NH 4 + -N, NO 3 --N, NO 2 --N, COD, MLSS, and MLVSS were measured according to Standard Methods [19]. The NH 4 + -N, NO 3 --N, and NO 2 --N were analyzed, respectively, by the HANNA HI 93715,HI 93728, and HI 93708 instrument.…”

“…Além disso, em peneiras moleculares tais como zeólitas, a difusão ou migração de moléculas através dos poros e cavidades (dentro dos cristais) exerce um papel importante e muitas vezes dominante 22 . A influência do tamanho de partícula de zeólitas naturais foi estudada por pesquisadores 23,24 e observou-se que, em um reator batelada, o tamanho da partícula zeolítica não afetou a taxa de remoção do cátion no equilíbrio, porém estas taxas foram significativamente afetadas para os tempos iniciais de contatos.…”
