Langmuir isotherms of diazepam on glass surfaces.

open access: yesChemical and Pharmaceutical Bulletin, 1983
The adsorption of diazepam dissolved in distilled water, 5% dextrose solution, normal saline, Ringer's solution and lactate Ringer's solution on porous glasses with controlled surface area was investigated. The adsorption phenomena principally obeyed the Langmuir adsorption isotherm. The reciprocal plots of the amount of adsorption vs. concentration of

Impact of methane adsorption on tight rock permeability measurements using pulse-decay

open access: yesPetroleum, 2019
The permeability of the rock is usually measured by the injection of gas using Darcy's flow model (pulse-decay). For oil formations, helium and nitrogen are the most common gases used to measure the permeability of the rock.

Study of Adsorption-Desorption on Batik Industrial Dyes (Naphthol Blue Black) on Magnetite Modified Humic Acid (HA-Fe3O4)

open access: yesJurnal Kimia Sains dan Aplikasi, 2020
The rapid development of the batik industry can pollute water resources and become an increasingly severe problem. This research studies the adsorption-desorption of naphthol blue-black (one of the dyes in batik liquid waste) by magnetite modified humic ...

Adsorption of Methyl Orange and Amoxicillin from Water using Metal-organic Framework Prepared from Solvothermal Mixing of Zn ions and 1,4-Benzenedicarboxylic Acid Moieties

open access: yesJournal of Applied Sciences and Environmental Management, 2023
In this study, we determined the capacity of metal organic framework, which we prepared by the solvothermal mixing of Zn ions and 1,4-benzenedicarboxylic acid (Zn/BDC) moieties to adsorb methyl orange (MO), and amoxicillin (AMX).

Dual‐Ligand Metal‐Organic Frameworks via In Situ Amidoxime Engineering for Selective Ion Separation

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by microbial ion‐trapping mechanisms, a mild and universal strategy is developed to construct highly porous amidoxime‐functionalized MOFs. DFT calculations and molecular force measurements reveal that the dual‐ligand amidoxime configuration significantly strengthens Ga(III) affinity.

Unraveling Quantitative Sensing Mechanism and Predictive Molecular Metrics for High‐Performance OFET Amine Sensors

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a novel chloro boron subphthalocyanine/polymer blend OFET sensor achieving 0.005 ppb limit of detection for ammonia at room temperature and high selectivity against similar amines. An original theoretical framework is proposed to describe the sensing mechanism, relating analyte molecular volume and Lewis basicity to sensor ...

SEQUESTRATION OF CIPROFLOXACIN FROM AQUEOUS SOLUTIONS BY NANOCOMPOSITE OBTAINED VIA MORINGA OLEIFERA PODS AND FELDSPAR CLAY MODIFICATION [PDF]

open access: yesSTED Journal
The environmental hazards of antibiotics have captivated increasing research focus, but their environmental behaviours remain unclear in water sources. Thus, this study focused on exploring the interaction mechanisms between Moringa Oleifera pod-modified

Breakdown of Langmuir Adsorption Isotherm in Small Closed Systems

open access: yesLangmuir, 2023
For more than a century, monolayer adsorptions in which adsorbate molecules and adsorbing sites behave ideally have been successfully described by Langmuir adsorption isotherm. For example, the amount of adsorbed material, as a function of concentration of the material which is not adsorbed, obeys Langmuir's equation.

Relationship of Dye Adsorption Onto Biomass Activated Carbon Mixed Matrix Ultrafiltration: A Mass Transfer Model Study

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explored dye molecule adsorption from water, focusing on activated carbon in polymer membranes for purifying low‐quality water. Polyvinylidene fluoride (PVDF) membranes showed enhanced removal efficiency of methylene blue (MB) from 89.29% to 98.33% with biomass‐activated carbon (BAC).
