General description
EMPLURA® is our low-cost alternative to high-purity qualities. With EMPLURA we offer a range of solvents for a plurality of basic applications in non-regulated industries and for less demanding applications, preparative laboratory work and cleaning purposes. EMPLURA solvents provide adequate specifications with the most important parameters.
Application
- Occurrence of 1,4-dioxane in drinking water of China and its ecological and human health risk: An examination of the prevalence of 1,4-dioxane in China′s drinking water, with an assessment of the associated ecological and human health risks, relevant for researchers and policymakers focused on public health and environmental safety (Wang et al., 2024).
- Adsorption Behavior and Kinetics of 1,4-Dioxane by Carbon Aerogel: This research discusses the effectiveness of carbon aerogel in the adsorption of 1,4-dioxane, providing valuable data on adsorption kinetics and behavior, useful for material scientists and chemists working with advanced materials (Lu et al., 2024).
- Photosensitized covalent organic framework as a light-induced oxidase mimic for colorimetric detection of uric acid: This innovative approach using a framework that could potentially be adapted for 1,4-dioxane detection underscores the intersection of material science and analytical chemistry, which could intrigue researchers developing new analytical methods (Wang et al., 2024).
