55results about How to "Delay the oxidation process" patented technology

A cannabinoid composition having an excipient including α-tocopherol and at least one isolated cannabinoid having a purity of greater than 80%. The α-tocopherol inhibits oxidation, regulates viscosity of the composition, and improves bioavailability of the cannabinoid. The composition includes a carrier oil mixed with the excipient and cannabinoid. In one embodiment, the at least one cannabinoid is an isolated cannabinoid having a greater than 80% purity, and preferably greater than 90% purity. The at least one cannabinoid is selected from the group consisting of phytocannabinoids, endocannabinoids, synthetic cannabinoids, and combinations thereof. The cannabinoid may be derived from plants other than cannabis sativa, or synthesized from fungi, bacteria, yeast or other synthetic method. Preferably the α-tocopherol comprises at least 10% w / w of the composition.

The invention discloses a method for treating chlorinated organic pollutants in underground water by using a slow-release compound repair material. The method comprises the following steps: (1), preparing charcoal through high temperature pyrolysis; (2), pre-treating zero-valent iron through acid pickling; (3), adding water into the charcoal, then adding xanthan gum and an organic carbon source, and finally, adding zero-valent iron, and through steps of treating, obtaining the slow-release compound repair material; then treating chlorinated organic pollutants in underground water by adopting an in situ injection repairing method or an in situ PRB repairing method. According to the method provided by the invention, the xanthan gum with high mechanical strength and strong mass transfer performance is used as a novel slow release embedding medium, the physical adsorbent charcoal, the chemical reductant zero-valent iron and the bioreductive drug organic carbon source are taken as effective components for composite embedding, so that gel microspheres with stable structures are formed, and the method provided by the invention has the advantages of sustained release, simple and convenient operation, low cost, environment friendliness and the like, can effectively achieve physically, chemically and biologically collaborated and enhanced remediation, and can effectively remove target pollutants.
