Arsenic removal material by adsorption of electrochemistry strengthened nano ferro-manganese loaded carbon fiberand arsenic removal method by using same

The invention discloses arsenic removal material by adsorption of electrochemistry strengthened carbon fiber loaded nano ferro-manganese and an arsenic removal method by using the material. The material comprises a substrate material and nano ferro-manganese oxidesloaded on the substrate material through electrochemistry and electro-deposition; the substrate material can be carbon fiber yarns, carbon fiber felts or graphite carbon fiber felts, and the shape of the substrate material is cylindrical or flat-shaped; and when a three-dimensional electrode is used, the substrate material is activecarbon. The arsenic removal material is prepared by performing ferro-manganese metal salt surface electro-deposition on the substrate material by electrifying. The arsenic removal method comprises the following steps of: carrying out coupling electro-absorption in the process of arsenic removal by chemical absorption, and strengthening the arsenic removal effect by using the electro-absorption action of a charging capacitor in the absorption process; applying reverse current to facilitate arsenic desorption on a surface of ferro-manganese hydrated oxide in a regeneration process, and simultaneously applying high voltage to perform hydrolysis, hydrogen generation and oxygen evolution so as to facilitate activity regeneration of the ferro-manganese oxide. With the adoption of the material and the method, the high absorption effect and the quick regeneration capability can be achieved.

Method for preparing total ginkgo flavone glycosides slow-release capsules by applying attapulgite

The invention discloses a method for preparing total ginkgo flavone glycosides slow-release capsules by applying attapulgite, which comprises the following steps of: washing, drying and pulverizing gingko leaves into coarse powder; adding the gingko leaf coarse powder and petroleum ether with the weight ten times of the gingko leaf coarse powder into a container, refluxing and extracting for 1 hour, degreasing, filtering and drying; adding water with the weight ten times of the degreased gingko leaf coarse powder into the degreased gingko leaf coarse powder, boiling, decocting for 3 times, combining decocting liquids, filtering and concentrating to the relative density of 1.10; adding ethanol with the mass concentration of 95 percent into a concentrated liquid until the ethanol concentration is 70 percent, depositing, settling and filtering; adsorbing a filtrate through modified attapulgite to obtain the attapulgite loading total ginkgo flavone glycosides; and adding a pharmaceutical adjuvant material into the attapulgite loading total ginkgo flavone glycosides, and encapsulating into empty capsules to obtain the total ginkgo flavone glycosides slow-release capsules. The invention adopts the principle of adsorption separation and selects the modified attapulgite with strong adsorbability for the total ginkgo flavone glycosides to directly prepare a preparation without elution, the total ginkgo flavone glycosides slow-release capsules are slowly desorbed under the desorption action of a body fluid, steps are simplified, the production period is shortened, and the yield of products is improved.

Nanofilm Protective and Release Matrices

A modified atomic plasma deposition (APD) procedure is used to produce amorphous, nonconformal thin metal film coatings on a variety of substrates. The films are porous, mesh-like lattices with imperfections such as pinholes and pores, which are useful as scaffolds for cell attachment, controlled release of bioactive agents and protective coatings.
