Method for determining content of tin in tungsten concentrate

Abstract: The invention discloses a method for determining the content of tin in a tungsten concentrate. The method comprises the following steps: smelting a tungsten concentrate sample through a composite smelting agent consisting of anhydrous borax, boric acid and zinc powder, leaching through thick hydrochloric acid, oxidizing leachate, filtering and separating to obtain a tin-containing solution, reducing the tin-containing solution through iron powder, titrating a reaction solution to an endpoint through a potassium iodate standard solution by taking a starch-potassium iodide solution as an indicator, and calculating the mass percentage of tin in the tungsten concentrate according to the titration result. The determination method is simple in process, low in cost, and capable of fast and accurately determining the content of tin in the tungsten concentrate and overcoming the defects of conventional methods for determining tin in the tungsten concentrate in the prior art, for instance, a potassium iodate volumetric method is complicated in determination process and inaccurate in determination, and an atomic absorption spectrometry method needs expensive advanced instruments and is large in testing cost.

Determination of ranitidine using potassium iodate and dichlorofluorescein

Abstract: Two methods for determining ranitidine hydrochloride (RNH) in pure drug and in formulations using potassium iodate and dichlorofuorescein are described Titrimetry involves the oxidation of RNH by a known excess of potassium iodate in acidic conditions followed by iodometric determination of surplus iodate In spectrophotometry also, the drug is oxidized by a large excess of iodate and the iodine released is oxidized to ICl 2 - in the presence of chloride ions, and is used to iodinate 2,7-dichlorofluorescein dye and the amount of iodinated dye is measured Reaction conditions of both methods have been optimized In titrimetry, the reaction stoichiometry has been established and the reaction scheme of the spectrophotometric method is given Titrimetry is applicable over 1-16 mg range In spectrophotometry, the system obeys Beer's law for 5-50 μg mL - 1 The molar absorptivity and Sandell sensitivity were calculated to be 388×10 3 L Mol - 1 cm - 1 and 572 ng cm - 2 , respectively The calculated limits of detection and quantification were 214 and 715 μg mL - 1 , respectively The proposed methods were applied successfully to the determination of RNH in pharmaceutical preparations with recoveries in the range of 9828 ′ 088 to 103 ′ 196% (titrimetry) and 9946 ′ 188 to 10258 ′ 073% (spectrophotometry) The reliability of the assay was established by parallel determination by an established procedure and by recovery studies using standard-addition technique

Method for preparing poultry feed additive compound mineral substance

Abstract: The invention discloses a method for preparing a poultry feed additive compound mineral substance, and belongs to the technical field of poultry feed additives. The mineral substance comprises the flowing elements: calcium hydrophosphate, sodium chloride, potassium citrate, potassium sulfate, magnesium sulfate, manganese carbonate, ammonium ferric citrate, zinc carbonate, copper carbonate, potassium iodate, sodium selenite and potassium chromium sulfate. In the compound mineral substance, the potassium iodate replaces the conventionally added potassium iodide to serve as the source of iodine element, the iodine element loss caused by decomposition and volatilization of the potassium iodide is prevented, the function of keeping the iodine element for a long time can be realized, and the production, processing, sales and feeding are facilitated. The addition amount of the mineral substance in the conventional poultry feed is 1/1,000-2/1,000; and experiments show that the mineral substance can stimulate the appetite of livestock and promote growth.

Iodine alginate aqua medical fertilizer and preparation method thereof

Abstract: The invention discloses an alga iodic acid aqueous medical fertilizer and a preparation method thereof. Each liter of the aqueous medical fertilizer comprises the following raw materials by mass: 20 to 30 g of alginic acid, 10 to 30 g of mannite, 8 to 72 g of potassium iodide, 1.6 to 15 g of potassium iodate, 2 to 18 g of iodine, 100 to 150 g of monopotassium phosphate, 44 to 71 g of anhydrous borax and the balance being water. The preparation method comprises the following steps: (1) the raw materials are taken out for standby according to the mass above; (2) the anhydrous borax is dissolved in water to obtain a borax liquid; (3) the alginic acid is placed in the borax liquid, is evenly mixed, is added with the mannite and the monopotassium phosphate, and is stirred and dissolved to obtain a standby liquid A; (4) the potassium iodide, the potassium iodate and the iodine are placed in the water and are dissolved to obtain a standby liquid B; and (5) the standby liquid A and the standby liquid B are evenly mixed and stirred; after stirring and precipitation, a supernatant liquid is obtained and is the alga iodic acid aqueous medical fertilizer. The alga iodic acid aqueous medical fertilizer is suitable for various crops, is safe and reliable, has no pollution, no residue and no harm, is not influenced by geographical environment and climate, can promote growth of the crop, improve adverse resistance and the like.
