Isotherm and Kinetics of Fe(II) Adsorption onto Chitosan in a Batch Process [PDF]

Iranica Journal of Energy and Environment, 2011
In this study removal of Fe(II) by chitosan adsorbent was experimentally investigated in a batch system. The adsorbent dose and pH of the metal solution was fixed at 0.15 g and 4, respectively.

Second-Order Pseudo-Hermitian Spin-1/2 Bosons

Universe
The canonical quantization of a field theory for spin-1/2 massive bosons that satisfy the Klein–Gordon equation is presented. The breakdown of the usual spin–statistics connection is due to the redefinition of the dual field, rendering the theory pseudo ...

Predictor Design of a Novel Grey Model PGM21 Using Pseudo Second-Order Information

JSME International Journal Series C, 2006
A novel grey model, called pseudo-GM(2,1) or PGM21 for simplicity, is developed to improve the prediction accuracy for a non-monotone sequence by modifying the GM(1,1) model with a remedial term. Since the remedial term consists of two development coefficients, it can be treated as a kind of second-order information, called the pseudo second-order ...

Generation Mechanism and Characteristic Analysis of Dual-Frequency Pseudo-Signal Interference of the Swept-Frequency Radar

International Journal of Antennas and Propagation, 2022
In order to master the law of the pseudo-signal interference effect of dual-frequency electromagnetic radiation in typical radar equipment, a certain type of Ku-band swept-frequency ranging radar was used as the test object to carry out single-frequency ...

Biosorption characteristics of Pennisetum glaucum for the removal of Pb(II), Ni(II) and Cd(II) ions from aqueous medium

Green Chemistry Letters and Reviews, 2017
Kinetics and thermodynamic studies were carried out for the removal of heavy metals (Pb+2, Ni+2 and Cd+2) from aqueous solution by using Pennisetum glaucum. Surface morphology and elemental analysis were investigated with scanning electron microscope and

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.
