Determination of silica concentration is an adaptation of the ASTM D859 method of the heteropoly blue method. The reaction between silica and reagents causes a blue tint in the sample which is proportional to the silica concentration.

The HI38067 is a chemical test kit that determines the silica concentration in two ranges: 0 to 40 mg/L and 0 to 800 mg/L. The HI38067 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents for perform approximately 100 tests. Features at-a-glance Complete setup All required materials are included with the test kit, such as the glass vials, plastic pipette, reagent bottles and packets, and Checker® disc. High resolution Readings from 0 to 40 mg/L are determined to 1 mg/L resolution. Readings from 0 to 800 mg/L are determined to 40 mg/L resolution. Replacement reagents available There is no need to buy a new kit when reagents are exhausted. The HI38067-100 can be ordered to replace the reagents supplied with the kit. Significance of Use Silica is found in all natural waters in the dissolved mineral form. Silica is only slightly soluble in water and can be found as ionic silica, silicates, or colloidal or suspended particles. The solubility of silica is highly dependent on pH, temperature and pressure. Silica's presence in industrial applications, particularly high pressure turbines, is undesirable because of the scaling caused by the elevated temperature and pressure. Heating systems and reverse osmosis plants also require monitoring of silica to ensure process efficiency.
