Phosphonate Testing in Hard Water - Mining
Testing phosphonates in hard water can be difficult due to interference from high levels of calcium. Here we present a phosphonate test method for hard water samples. The method is based on a chemical masking of the calcium. The WAT hard water phosphonate test uses C30 Spectrophotometer to measure the chromogen PMB and digital thermoreactor to digest the phosphonate compound. The thermoreactor capacity of 16 simultaneous vials provides for running critical data quality assurance samples.
