The fate and chemical forms of lime after application in an aquatic environment were studied for the duration of 12 weeks. In freshwater, critical compounds were CaCO3 and Ca(OH)2; relative composition of CaCO3 in precipitants was increasing between weeks 2 and 8, and then reached approximately 60%. In seawater, CaCO3, CaSO4 · 2H2O and Mg(OH)2 were recognized as critical constituents; composition of CaCO3 showed maximum between weeks 2 and 6, and CaSO4 · 2H2O began to increase from week 8. Final compositions of three compounds were 66.7% for Mg(OH)2, 19.7% for CaSO4 · 2H2O and 13.6% for CaCO3. |
