Ph of sediment
WebbSediment pH, redox potential, and porewater metal concentrations were monitored over 40 days. Depth profiles were also measured to investigate stratification. A single pH adjustment to pH 7 and 8 initially counteracted the pH change caused by metal additions, however, pH continued to decrease slowly thereafter. WebbpH was determined with a combined electrode. pH of sediment was measured directly in wet sediment after sectioning of the sediment core. Comparing pH meas urements in wet sediment with pH of supernatant water after shaking wet sediment with distilled water (1:1 on a volume basis) consistently gave pH values 0.2-0.3 units higher in supernatant ...
