摘要
Abstract
In this study,total chromium of wastewater samples collected from different technological processes in tannery industries were determined by using flame atomic absorption spectrophotometric method.The effects of different measuring tools,sampling amount,digestion methods and retention periods on test results were investigated.The results showed that sampling heterogeneity caused by suspended solids in water samples led to obvious difference of test results.The test results of total chromium in tannery wastewater by using different digestion methods were comparable,and the addition of fixing agent could keep the test data of water samples stable.关键词
