Nuclear Science and Techniques 2024年第1期35卷 59-72页

Ltd.Cangnan 325800China Jiangxi Province Key Laboratory of Polymer Micro/Nano Manufacturing and Devices East China University of TechnologyNanchang 330013China School of Nuclear Science and Engineering East China University of TechnologyNanchang 330013China

To explore the kinetic adsorption under continuous and nonequilibrium states, an integration of continuous measurement and adsorption platform kinetics method was proposed, which was initially called the ICM-AP kinetics method, and a corresponding kinetic adsorption experimental method was developed. Adsorption experiments of europium(Eu) on Ca-bentonite,Na-bentonite, and the D231 cation exchange resin were performed using the ICM-AP kinetics method and continuous measurements. Because the kinetic experimental results observed in this study were different from those of traditional batch adsorption data, pseudo-first-order or pseudo-second-order kinetic models were unsuitable for fitting the experimental ***, a liquid membrane diffusion(LMD) model was developed based on the assumption of simultaneous adsorption/desorption to discuss the mechanism of kinetic adsorption. The kinetic adsorption mechanism was also studied by using *** results indicated that the proposed adsorption model can fit the experimental data more suitably, and the adsorption/desorption behaviors of Eu on bentonite and the D231 resin were simultaneously observed, suggesting that the adsorption kinetics of Eu(Ⅲ) was mainly dominated by hydrated Eu(Ⅲ) ions on the liquid membrane.

Two Ramsey-Turán Numbers of Small Independence Numbers

引用

Acta Mathematicae Applicatae Sinica 2024年

作者： Xin-yu hu qi-zhong LIN Center for Discrete Mathematics Fuzhou University

Given a forbidden graph H and a function f(n), the Ramsey-Turán number RT (n, H, f (n)) is the maximum number of edges of an H-free graph on n vertices with independence number less than f (n).For graphs G and H, the Ramsey number R(G, H) is the minimum integer N such that any red/blue edge coloring of the complete graph KNcontains either a red G or a blue H. Denote G+H by the join graph obtained from disjoint G and H by adding all edges between them completely. We first show that for any fixed graph H, if there are two constants p:=p(H)> 0 and q:=q(H)> 1 such that R(H, Kn)≤(pnq)/(log n)q-1, then RT(n, K2+H, o(n1/q(log n)1-1/q))=o(n2), which extends several previous results. Moreover, we show that for any fixed forest F of order k≥3, and for any 0 <δ <1 and sufficiently large n, RT(n, F+F, nδ)≤n(2-(1-δ)/「(k-1)(2-δ)/(1-δ)」).As a corollary, we have an upper bound for RT(n, K2,2,2, nδ) for any 0 <δ <1.
