assay of barium sulphate

The amount of sulphate is determined quantitatively as barium sulphate, BaSO4 by gravimetric analysis. The results will be reported as a certificate of analysis together with a summary report of the procedures and results. Published by Elsevier Inc. All rights reserved. Data-Time Group (DTG) 3. Calcium, strontium, and silica do not interfere. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Gravimetric analysis—barium chromate precipitation, Atomic absorption spectrometry—calcium, strontium analysis, Strontium, lead extraction—gastrointestinal fluids. Aim To produce a pure sample of Barium Sulphate (BaSO4) of at least 0.50 grams. Barium sulphate (the name barium coming from the Greek word for heavy, barys) is a white or yellowish odourless powder which has many medical and industrial applications. They involve qualitative identification tests for barium and sulphate, pH, heavy metals, limit tests for sulphide, acid-soluble substances and soluble barium salts plus a quantitative gravimetric assay for barium as the insoluble chromate salt. The mass of Barium in the whole of the given solution is calculated knowing that 233.36 g of barium sulphate contains 137.36 g of barium. Assay— Accurately weigh not less than 0.58 g and not more than 0.62 g of Barium Sulfate in a tared platinum crucible, add 10 g of anhydrous sodium carbonate, and mix by rotating the crucible. It has also found application in clutch and brake linings due to its high temperature stability. The calcium and strontium content may be determined by atomic absorption or X-ray fluorescence and silica by a colorimetric procedure. Using the remaining test tube, add 0.1 ml of HCl into the solution. © The precipitated barium sulphate is separated and weighed. Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4.It is a white crystalline solid that is odorless and insoluble in water.It occurs as the mineral baryte, which is the main commercial source of barium and materials prepared from it. An alternative, more-direct method, in … Apparatus & Materials Chemicals used: Barium Nitrate, Ba(NO3)2 Sulphuric Acid, H2SO4 Lab equipment used: Glass beakers (2) Funnel (1) Filter paper (5) Conical flask (1) 5. By continuing you agree to the use of cookies. Cool, place the crucible in a 400-mL beaker, add 250 mL of water, stir with a glass rod, and heat to dislodge the melt. Barium sulphate precipitate is form when Barium Chloride is added excessively to a hot given Sulphate solution slightly acidified with concentrated Hydrochloride acid. Abstract A method suitable for compendial assay of barium sulfate USP has been developed. Chem. Barium is separated as the carbonate and precipitated as the chromate. Although barium and all of its soluble compounds are toxic, barium sulphate can safely be used in medical devices and procedures due to its lack of solubility in water or other body fluids. From the mass of BaSO 4, the amount of sulfate present in the original sample is calculated. … Accurate purity determinations are required at several stages of product manufacture, to ensure product safety and meet regulatory requirements. The calcium and strontium content may be determined by atomic absorption or X-ray fluorescence and silica by a colorimetric procedure. A method suitable for compendial assay of barium sulfate USP has been developed. Taking one of the remaining test tubes, add 0.1 mL of BaCl2 into the solution and mix well. After that preparation step, all additional sulfate from your sample will precipitate when the … If HCl is present in the solution, bubbling and a strong smell of ammonium should be present. The chemical analysis of barium sulphate is covered by very similar test methods in both the US and EU pharmacopoeias. 4. Pharmacopoeial Analysis of Barium Sulphate to USP 29 - Test Method. Barium is separated as the carbonate and precipitated as the chromate. This determination consists of slowly adding a dilute solution of barium chloride to a hot solution of the sulphate slightly acidified with concentrated HCl. They involve qualitative identification tests for barium and sulphate, pH, heavy metals, limit tests for sulphide, acid-soluble substances and soluble barium salts plus a quantitative gravimetric assay for barium as the insoluble chromate salt. Barium sulfate is minimally soluble, though, and to saturate the working reagent with soluble barium sulfate, you have to add a little of the sulfate standard to reagent A (which only contains barium). It is for example used as a filler in root canal fillings and bone cements. If the mixture has a white precipitate of Barium Sulfate, then the solution has a sulphate ion present (4). An in vitro study of the extractability of strontium and lead from barium sulfate into simulated gastric and intestinal fluids was performed. The mass of Barium in the whole of the given solution is calculated knowing that 233.36 g of barium sulphate contains 137.36 g of barium. The ability of barium sulphate to absorb both gamma and X-radiation makes it particularly useful as a radio-opaque substance within the medical area, a common example being the ‘barium meal' suspension or enema used during X-ray procedures of the gastrointestinal tract to increase the contrast of the image. This assay is based on the precipitation of insoluble barium sulfate which is measured turbidimetrically. Experiment Title: Synthesis of Barium Sulphate (BaSO4) 2. Method 1. Copyright © 2020 Elsevier B.V. or its licensors or contributors. The chemical inertness of barium sulphate makes it suitable for use as a filler in plastics, paint, rubber and resins, as a pigment in photographic papers and, due to its radio-opaque properties, as a component of concrete to screen nuclear reactors.

A method suitable for compendial assay of barium sulfate USP has been developed. BioAssay Systems' Sulfate Assay Kit (DSFT-200) measures sulfate concentration in biological fluids by quantitative formation of insoluble barium sulfate in polyethylene glycol. 2020 Calcium, strontium, and silica do not interfere. Testing & Characterization » Barium sulfate which forms as a crystalline precipitate, is collected on a suitable filter, washed with water, then ignited and weighed.
