TL;DR: In this article, a powder is obtained by grinding a mixture of raw spinach, drying agent, and sand (1:1:2) that can be extracted directly into acetone in 10 minutes to provide a sample suitable for chromatographic analysis.
Abstract: A direct method of extracting plant pigments from spinach leaves into a dry organic solvent is presented. A powder is obtained by grinding a mixture of raw spinach, drying agent, and sand (1:1:2) that can be extracted directly into acetone in 10 minutes to provide a sample suitable for chromatographic analysis. This method avoids liquid–liquid extractions and subsequent drying as is found in previously reported methods. Removal of the magnesium ion from chlorophyll pigments was observed by treating the acetone extract with a strong ion-exchange resin for three minutes. The loss of magnesium ion is often observed as a degradation product of chlorophyll samples. An improved solvent system consisting of petroleum ether, cyclohexane, ethyl acetate, acetone, and methanol in 60%, 16%, 10%, 10%, and 4% quantities, respectively, is also reported. TLC separation using this extraction method and solvent system allows for the clear separation of chlorophyll a and b from all other extracted pigments.

TL;DR: A new heterogeneous Fenton-like system, consisting of supported Au catalysts and hydrogen peroxide, was proved to be effective in removing low level organic compounds such as phenol, ethanol, formaldehyde, and acetone in aqueous solution.
Abstract: A new heterogeneous Fenton-like system, consisting of supported Au catalysts and hydrogen peroxide, was proved to be effective in removing low level organic compounds (ca. 100 ppm) such as phenol, ethanol, formaldehyde, and acetone in aqueous solution. Among all gold catalysts the Au/hydroxyapatite (Au/HAp) exhibits the highest activity, and even better than the conventional iron ions exchanged zeolite (Fe/ZSM-5) catalyst. In particular, unlike the limited operational pH range (pH: 2∼5) for the other heterogeneous Fenton catalysts such as Fe/ZSM-5, Au/HAp shows higher stability even in strong acid solution (pH ∼ 2), due to almost no leaching of active metal from supports into solution. It can be potentially applied in treating the industrial wastewaters with strong acidity and purifying drinking water. In addition, in the case of complete oxidation of phenol, a plausible route was suggested for deep understanding of this process.
