1.1This test method covers the on-line determination of soluble silica in water by colorimetric analysis using the molybdenum blue method, also known as the heteropoly blue method.
1.2This test method is applicable for silica determination in water with silica concentrations within 0.5–5000 ppb (μg/L).
1.3This test method covers the determination of soluble silica SiO2 (silicon dioxide) or silicates in water. Soluble silica compounds are considered molybdate reactive silica. This test method does not cover the determination of colloidal or polymeric silica, which is considered non-molybdate reactive silica.
1.4This test method does not cover the laboratory or grab sample measurement of silica in water. Refer to Test Method D859.
1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
