Web15 de dez. de 2024 · The meso-Beta (weight ratio of dry gel/H 2 O: 2.5/1) shows extremely high adsorption efficiency of 52% within 40 s for methylene blue, which is 4 times than that of bulk-Beta (Fig. 5 a–b). Moreover, the dye molecule can be removed completely within 15 min by meso-Beta, while the removing efficiency of bulk-Beta is only 38%.

We need to specify our prior, which for this hierarchical model means that we have to specify the conditional distribution, g ( θ i ∣ ϕ), as well as g ( ϕ). We could assume a Beta prior for ϕ; the one we chose in our original nonhierarchical model would be a good choice. ϕ ∼ Beta ( 1.1, 1.1).
