Absorption of chemicals in amorphous trisresorcinarene
Chemical Communications, 2020Trisresorcinarene is an interesting class of macrocyclic host. Its unique structure and insolubility allow to function as a amorphous solid absorbent capable of absorbing various aromatic and aliphatic hydrocarbons.

Percutaneous absorption of chemicals from fabric (textile)
Journal of Applied Toxicology, 2020AbstractPercutaneous penetration of chemicals from clothing can result in both acute and chronic toxicities. Although personal protective equipment composed of nonwoven material can provide thorough protection, it is often uncomfortable under normal occupational conditions.

Absorption of chemicals through compromised skin
International Archives of Occupational and Environmental Health, 2009Skin is an important route of entry for many chemicals in the work place. To assess systemic uptake of a chemical in contact with the skin, quantitative information on dermal absorption rates of chemicals is needed. Absorption rates are mainly obtained from studies performed with intact, healthy skin.

Predicting the absorption of chemical vapours
Advanced Drug Delivery Reviews, 2013The focus of this review is on the systemic absorption of vapours via skin, including experimental data as well as regression and pharmacokinetic models. Dermal contribution ratios (DCR), i.e. amount absorbed through skin relative to total intake (skin and inhalation) at specified conditions, could be identified or calculated from published data for 33

Hydrogen sulphide chemical absorption
Chemical Engineering Science, 1964Abstract The chemistry of the processes of H 2 S absorption in aqueous hydroxide solutions and in aqueous carbonate-bicarbonate buffer solutions is studied, and theoretical equations for the rate of absorption are derived. Experimental results are in good agreement with theory.

For a toxic chemical to be harmful, it must first travel from the environment to a specific target site within the body. Much of this journey happens through the deceptively simple process of diffusion: molecules migrating away from their source. Examples of diffusion are all around us, from salts dissolving into water to fumes dispersing from a ...

Interfacial turbulence accompanying chemical absorption
The Canadian Journal of Chemical Engineering, 1977AbstractAbsorption rates for carbon dioxide into aqueous solutions of EDA and MEA with and without adding surface active agent were measured in a laminar liquid‐jet apparatus to check and verify the Marangoni effect. In addition, experiments were conducted for the tracer desorption of ethylene from aqueous EDA and MEA solutions into carbon dioxide or ...

Percutaneous Absorption of Volatile Chemicals
1997Abstract : The purpose of this project was to assess the percutaneous absorption of two volatile organic compounds, chloropentafluorobenzene (CPFB) and dichlorobenzene (DCB) in the isolated perfused porcine skin flap (IPPSF) model. An independent theoretical goal was to begin to develop a mathematical framework to assess vehicle-compound interactions ...
