Dependence of silver availability on water quality parameters
- Clemson Univ., SC (United States). Inst. of Wildlife and Environmental Toxicology
The availability of silver in varying water quality conditions such as chloride content, hardness, alkalinity, total organic carbon and pH was investigated during a test to measure acute toxicity to Daphnia magna and Pimephales promelas. Water quality parameter treatments included four chloride concentrations (3, 10, 20, 40, mg/L), two hardness treatments (100, 200 Mg CaCO{sub 3}/L), four humic acid concentrations (0, 2, 5, 10 mg/L), a pH of 7.5, and alkalinity at 2 {times} 10{sup {minus}3} eq/L. Varying silver concentrations were added to,each treatment. Total silver concentrations were determined using atomic absorption spectrophotometry. Analytical procedures to determine water quality conditions followed modified ASTM methods. Water quality effects on free and bound silver will be discussed.
