  • Enzymatic Nitrate Determination Now an ASTM Standard Method

    NECi enzymatic method for nitrate determination is now an ASTM International Standard Method.  This method is meant to replace methods D1254 (Nitrite) and D992 (Nitrate).   Method D1254 uses a reagent which is considered to be a possible carcinogen. Method D992 is mentioned by ASTM to "have relatively large errors when used in wastewaters and also has greater manipulative difficulties" ...

  • ASTM D3454 - 11 standard test method for radium-226 in water

    The most prevalent of the five radium isotopes in ground water, having a half life greater than one day, are 226Ra and 228Ra. These two isotopes also present the greatest health risk compared to the other naturally occurring nuclides of equal concentrations if ingested via the water pathway. Although primarily utilized on a water medium, this technique may be applicable for the ...

  • ASTM D516 - 11 standard test method for sulfate ion in water

    The determination of sulfate is important because it has been reported that when this ion is present in excess of about 250 mg/L in drinking water, it causes a cathartic action (especially in children) in the presence of sodium and magnesium, and gives a bad taste to the water. 1. Scope 1.1 This turbidimetric test method covers the determination of sulfate in water in the ...

  • ASTM D1293 - 12 Standard Test Methods for pH of Water

    The pH of water is a critical parameter affecting the solubility of trace minerals, the ability of the water to form scale or to cause metallic corrosion, and the suitability of the water to sustain living organisms. It is a defined scale, based on a system of buffer solutions with assigned values. In pure water at 25°C, pH 7.0 is the neutral point, but this varies with temperature and the ...
