  • Publication number: 20110240558
    Abstract: Disclosed is a method for recovering a corrosion preventive agent in an electrodischarge machining liquid supply apparatus. The method includes the step of passing a first electrodischarge machining liquid having a corrosion preventive agent added there to through, an ion exchange resin column to maintain a suitable specific resistance of the first liquid, and the step of passing a second liquid free from a corrosion preventive agent through the ion exchange resin column to desorb the corrosion preventive agent adsorbed in the ion exchange resin column. The second liquid is, for example, tap water or a machining liquid having a low corrosion preventive agent concentration. The corrosion preventive agent is, for example, adenine which is a purine base.

  • Patent number: 7883625
    Abstract: The present invention relates to a method for removing oil from water or a solid surface. This involves contacting the water or the solid surface with a substance in the form of a sheet and having a high humate level under conditions effective for the substance to absorb oil from the water or the solid surface. The substance, having absorbed oil, is then recovered from the water or solid surface. In an alternative embodiment this method can be carried out where the substance is manure which may or may not be in the form of a sheet.

  • Publication number: 20110023711
    Abstract: The problem to be solved by the present invention is to provide a monolith adsorbent which can adsorb a target sample easily in a short time or regardless of whether the amount of the sample is small or large and extract the sample with a small amount of solvent, and easily secure the sample necessary for analysis, and a method and an apparatus for adsorption and retention using the same. The present invention, as the means for solving the problem, is a monolith adsorbent formed by allowing a monolith structure body to contain an adsorbing material such as activated carbon or graphite, exposing the adsorbing material on the surface of the structure body and further surface-treating the surface of the monolith structure body with a hydrophobic or hydrophilic compound or a resin.

  • Patent number: 7879244
    Abstract: A method for the removal of a substance, which has a negative charge and which is present in an aqueous liquid (I). The method comprises the steps of: (i) contacting the liquid with an anion-exchanger (1) that comprises mixed mode anion-exchanging ligands in which there is a positively charged nitrogen allowing binding of the substance to the anion-exchanger; and (ii) desorbing said substance from said anion-exchanger. The characteristic feature is that (A) the mixed mode ligands have a thioether linkage within a distance of 1-7 atoms from their positively charged atom, and (B) the anion-exchanger (1) (i) is capable of binding the substance of interest in an aqueous reference liquid (II) at an ionic strength corresponding to 0.25 M NaCl, and (ii) permits in the pH interval 2-12 a maximal breakthrough capacity for the substance which is ?200% of the breakthrough capacity of the substance for Q-Sepharose Fast Flow (anion-exchanger 2).

  • Publication number: 20100326921
    Abstract: In the present, a procedure of obtaining adsorbent from a waste material and its use are disclosed. This invention provides a natural waste material, specifically avocado seed, its preparation and use for the filling of columns used in the elimination of contaminants present in wastewater. The particles have an irregular shape and variable size for filling columns of different diameter and length. The adsorbent has the sufficient hardness for avoiding a particle collapse. The material does not rot, is re-generable and ecological. In the present invention the preparation of the adsorbent, its pre-activation, carbonization and application to eliminate the color of textile wastewater is disclosed. The color elimination from textile wastewater, as well as decrease of salts, total suspended solids, chemical oxygen demand (COD) and total organic carbon (TOC), is carried out passing the textile wastewater through a column filled with the prepared adsorbent.
