Elementary Steps in Steady State Kinetic Model Approximation for the Homo-Heterogeneous Photocatalysis of Carbamazepine

Clean Technologies, 2023
Elucidating physicochemical processes in the degradation of pollutants may optimize their removal from water sources. Although the photodegradation of carbamazepine (CBZ) in Advanced Oxidation Processes (AOPs) has been widely studied, there is no ...

Pseudo-Gaussian and Rank-Based Tests for First-Order Superdiagonal Bilinear Models in Panel Data

Revstat Statistical Journal, 2021
In this paper, locally asymptotically optimal (in the H´ajek-Le Cam sense) parametric, pseudo-Gaussian and rank-based procedures are proposed for the problem of testing randomness against first-order superdiagonal bilinear panel dependence (in large n ...

Trade-Off between Degradation Efficiency and Recyclability: Zeolite-Enhanced Ni_3−xCo_xS₄ Catalyst for Photocatalytic Degradation of Methylene Blue

Molecules
We herein report successful syntheses of both nickel cobalt sulfide (NCS) and its composite with zeolite (NCS@Z) using a solvothermal method. Techniques such as EDX analysis, SEM, and molar ratio determination were used for product characterization.

Kinetics of reaction of 5,5′-dithiobis(2-nitrobenzenzoate) with CysF9[93]β sulphydryl group of sheep haemoglobins at neutral and physiological pH ranges

Journal of Saudi Chemical Society, 2016
The kinetics of the reaction of 5,5′-dithiobis(2-nitrobenzoate) (DTNB) with CysF9[93]β sulphydryl group of the sheep haemoglobins were studied at neutral and physiological pH (6.8 ⩽ pH ⩽ 7.6) ranges under pseudo first order conditions.

Determination of parameters and kinetic evaluation for chromium (VI) removal using four resins

Eclética Química
This research aimed to identify optimal studied variables for chromium (VI) removal using four resins (IRA 96, IRA 400, DOWEX 1x8, and LEWATIT). A 1,5-diphenylcarbazide method was used for the quantification of chromium (VI).
