A biomedical application of activated carbon adsorption: An experiment using acetaminophen and n-acetylcysteine

Abstract

A description of an experiment that illustrates an interesting biomedical application of adsorption from solution and demonstrates some of the factors that influence the in vivo adsorption of drug molecules onto activated carbon.

Activated Carbon from Various Agricultural Wastes by H3PO4 Activation: Preparation and Characterization

“…ACs with micropores and interconnecting mesopores may finding a wide range of industrial applications, including the adsorption of pollutants in gaseous phase 29 or liquid phase 30, gas separation and storage, 31 as electrodes in different energy storing devices 32, as catalyst supports in a variety of chemical syntheses 33, as supercapacitor electrodes, 34 and in biomedical applications as adsorbents and drug carriers 35.…”

A Simple Adsorption Experiment

“…The phenomenon of adsorption is a key topic included in most physical chemistry courses and textbooks. , The adsorption of a molecule into a solid surface is the basis for a broad spectrum of chemical applications and technologies, such as the removal of contaminants from wastewater, chromatography, and heterogeneous catalysis. − The importance of this phenomenon and the existence of either theoretical models (such as Langmuir or BET isotherms) or experimental models (such as Freundlich and Temkin isotherms), which make it possible to explain the adsorption equilibrium process, , has led to the publication of a considerable number of related experiments in this Journal − and in many chemistry laboratory manuals. − …”

Chemical Characterization of Activated Carbon Fibers and Activated Carbons

“…For instance, the data are crucial to explain the results in studies of liquid-phase adsorption, such as those previously published in this Journal (1)(2)(3) or to analyze samples produced by chemical modification methods such as oxidation in the liquid phase with nitric acid (4), sulfuric acid (5), hydrogen peroxide (5), or by thermal treatments under controlled atmosphere (6,7). For instance, the data are crucial to explain the results in studies of liquid-phase adsorption, such as those previously published in this Journal (1)(2)(3) or to analyze samples produced by chemical modification methods such as oxidation in the liquid phase with nitric acid (4), sulfuric acid (5), hydrogen peroxide (5), or by thermal treatments under controlled atmosphere (6,7).…”
