Chlorinated Hydrocarbons in Drugs: Chlorobutanol

open access: yesJournal of AOAC INTERNATIONAL, 1967
Abstract A method for chlorobutanol, a widely used antibacterial preservative for aqueous solutions of drugs, was studied collaboratively by 8 laboratories. In the method, chlorobutanol is eluted with carbon disulfide from a Celite column and determined by infrared spectrophotometry and/or gas-liquid chromatography.

Pre‐treatment with extraction solvent yields higher recovery: Method optimization for efficient determination of polycyclic aromatic hydrocarbons in organic‐rich fine‐textured wastes

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Fluid fine tailings (FFT) contain numerous organic compounds, including polycyclic aromatic hydrocarbons (PAHs). Growing concerns of PAH toxicity warrants monitoring for environmental consequences and natural attenuation. Conventional Soxhlet extraction yields low (∼50%–60%) recovery of PAHs (naphthalene, phenanthrene, pyrene, dibenzofuran ...

Interfacial properties of cellulose derivatives from guinea grass (Megathyrsus maximus)

open access: yesJournal of Surfactants and Detergents, Volume 28, Issue 4, Page 947-960, July 2025.
Abstract The utilization of sustainable feedstocks in surfactant production is crucial for reducing environmental impact, enhancing resource efficiency, and aligning with global efforts toward a circular economy and green chemistry. In this research, cellulose derivatives were synthesized by methylating cellulose fibers extracted from Guinea grass ...

Anaerobic Degradation of Chlorinated Hydrocarbons in Groundwater Aquifers or "Chlorinated Hydrocarbon Degradation"

open access: yes, 1997
Groundwater contamination by chlorinated hydrocarbons, such as tetrachloroethene (PCE) or trichloroethene (TCE), is a major concern throughout the United States. A developing strategy for the remediation of PCE and TCE contaminated aquifers is anaerobic biodegradation.

Mass spectrometry of dendrimers

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Mass spectrometry (MS) has become an essential technique to characterize dendrimers as it proved efficient at tackling analytical challenges raised by their peculiar onion‐like structure. Owing to their chemical diversity, this review covers benefits of MS methods as a function of dendrimer classes, discussing advantages and limitations of ...
