In Arnsberg, Sauerland area Germany, 40000 residents were exposed to PFOA-contaminated drinking water (500-640ng PFOA/l; May 2006). In July 2006, the PFOA-concentrations in drinking water were lowered significantly by activated charcoal filtering in the waterworks, mostly below the limit of detection (10ng/l). A first human biomonitoring study performed in autumn 2006 revealed that PFOA-concent...
Using commercially activated carbon, we developed a simple and effective direct chemical oxidation route to prepare good biocompatible multicolor photoluminescent carbon dots.
Previous research69 has shown that the Toth equation describes well the adsorption of hydrocarbons on carbon adsorbents, especially on Nuxit-Al charcoal. This fact is probably connected with the quasi-gaussian energy distribution function, which is related to T6th's equation. In this paper, the parameters of the above mentioned equation have been discussed once again and recent results on this ...
Radon adsorption by activated charcoal collectors such as PicoRad radon detectors is known to be largely affected by temperature and relative humidity. Quantitative models are, however, still needed for accurate radon estimation in a variable environment. Here we introduce a temperature calibration formula based on the gas adsorption theory to evaluate the radon concentration in air from the av...
BACKGROUND Activated charcoal (AC) is commonly used for the routine management of oral drug overdose. AIM To determine whether the routine use of activated charcoal has an effect on patient outcomes. DESIGN Randomized controlled unblinded trial. METHODS We recruited all adult patients presenting with an oral overdose at The Canberra Hospital, excluding only transfers, late presenters, tho...
Background: Rosa centifoliais commercially propagated by asexual means but in vitro propagation ensure the production of disease free and healthy plants and browning of explants creates hurdle in their multiplication. Objectives: The aim was to reduce oxidative browning of shoots of R. centifolia in MS medium during in vitro propagation. Materials and Methods: Axillary buds of R. centifolia we...
