Water Analyses contain elements, B, Si, S, and P
Water analysis data obtained from ICP measurements will contain concentrations for non metals like B, P, S, and Si. These elements do not exist in the water, rather they exist as dissolved ions. if you see these elements in the analysis, then you need to convert them to the following
Table 1 Converting element concentration to species for Brine or Water Analysis
ICP data | Aqueous Species | Formula to enter | Formula weight multiplier |
---|---|---|---|
B, boron | boric acid | H3BO3 | B (mg/l) * 5.71 = H3BO3 (mg/l) |
Si, Silicon | silica | SiO2 | Si (mg/l) * 2.14 = SiO2 (mg/l) |
P, Phosphorus..... | dihydrogen phosphate..... | H2PO4-1 | P (mg/l) * 3.13 = H2PO4 (mg/l) |
S, Sulfur | sulfate or sulfide | HS-1 or SO4-2 (cannot tell from total S only).... | S (mg/l) * 1.03 for HS-1 (mg/l) or |
S (mg/l) * 3.0 for SO4-2 (mg/l) |
