摘要: To provide a method and an apparatus for producing a sodium hypochlorite solution on-site at a high efficiency and at the initial cost and suppressing operating cost without any problems about impurities derived from raw material water and raw salt. A method of producing a sodium hypochlorite solution on-site in the vicinity of a physical plant where a sodium hypochlorite solution is used. In production of a sodium hypochlorite solution by feeding secondary salt water, in an electrolyzer comparted into an anode chamber and a cathode chamber with an ion-exchange membrane, to the anode chamber and allowing components in the anode chamber and the cathode chamber after electrolysis to react in a reaction tank, there are included respective steps of treating raw material water A with a cation-exchange resin B to generate purified water 5, dissolving raw salt D in the purified water to generate primary salt water E, performing an examination for confirming the presence or absence of a precipitate or suspended solid in the primary salt water, and directly performing chelating in the case of no precipitate or suspended solid contained in the primary salt water, or performing chelating after addition of an acid component for dissolution of the precipitate or suspended solid in the case of the precipitate or suspended solid contained therein, to generate secondary salt water 4.

摘要: An anti-microbial formulation for seed and crop application is a formulation including only between about 1 ppm and about 100 ppm hypochlorous acid; between about 1 ppm and about 300 ppm alkyl polyglycoside, wherein sufficient amount of alkyl polyglycoside is present such that the formulation has a pH between about 5.2 and about 7.8; and a remainder water. A method of manipulating the pH of the formulation and a method of treating seeds and crops with the formulation to restrict or eliminate microbial growth and proliferation is also described herein.

摘要: Provided are sodium hypochlorite pentahydrate crystals capable of long-term storage that have improved stability of sodium hypochlorite pentahydrate, which is effective as an oxidizing 5 agent or bactericide, in the vicinity of normal temperatures, and a method for producing the same. The sodium hypochlorite pentahydrate crystals are such that peaks appear at the locations of the angles of diffraction described in Table 1 of claim 1 over a range of 10°≤2θ (angle of diffraction)≤65° as measured by powder X-ray diffraction using a Cukα radiation source.

摘要: The purpose of the present invention is to provide a method for manufacturing a new disinfectant from sodium hypochlorite that has degraded in quality during storage. A method for manufacturing a novel disinfectant from a solution containing hypochlorite ions, chlorate ions, and chloride ions, wherein the method includes: a first reaction step for adding sulfuric acid to the solution and generating chlorine gas; a step in which, in a recovery liquid A, the generated chlorine gas is caused to react with sodium hydroxide or calcium hydroxide and recovered as hypochlorite ions; a second reaction step for adding, to a reaction mother liquid after the first reaction step, sulfuric acid having a higher concentration than that in the first reaction step, and generating chlorine dioxide gas; a step in which, in a recovery liquid B, the generated chlorine dioxide gas is caused to react with sodium hydroxide and hydrogen peroxide and recovered as chlorite ions; and a step for mixing the recovery liquid A and the recovery liquid B and obtaining a novel disinfectant.
