Separate and enrich water samples by using solid-phase extraction, and then conduct quantitative analysis by using the ICP-MS method for 14 species of tombarthite elements. The results show that after pretreatment, ICP-MS method could be used to measure the 14 species in water samples simultaneously and it is fast, high sensitive, 50 times of enrichment, 0.2 ng/L of method detection limit after enrichment, better precision, RSD < 5%; higher accuracy, and 93-104% of water recovery rate for simulative water samples.

AbstractA solid phase extraction technique for the determination of platinum(IV) at trace levels by inductively coupled plasma mass spectromA solid phase extraction technique for the determination of platinum(IV) at trace levels by inductively coupled plasma mass spectrometry (ICP-MS) was developed. The method was based on retention of platinum in a sample on silica gel modified with aminepropyl groups. The retention of platinum(IV) from the sample solution and the recovery of platinum with 1.0 mol L−1 thiourea solution were quantitative. The relative standard deviation (RSD) was calculated as 5% (n = 7) at the 10 ng L−1 level. The enrichment factor was found to be (50-fold) for 250 mL of water sample. Under optimum conditions, the method detection limit (MDL) was found to be 1 ng L−1 for platinum in water matrices. Recoveries of Pt from spike addition to atmospheric water samples were quantitative (80–95%). The present method was used for the determination of platinum in precipitation, throughfall and runoff water samples.
