Sl.No. Synosis Points
1 This standard (Part 35) prescribes the following methods for determination of silicon as silica (SiO2) in water and wastewater: a) Gravimetric method (is not recommended when samples contain less than 20 mg SiO2/l); b) Molybdosilicate method (measurable range is 0.4 mg SiO2/l to 25 mg SiO2/l); c) Heteropoly blue method (measurable range is 0.04 mg SiO2/l to 2 mg SiO2/l); d) Automated method for molybdate-reactive silica method (measurable range is 0 mg SiO2/l to 20 mg SiO2/l); and e) Inductively coupled plasma spectroscopy method.
