The influence of four calcium complexing substances, i.e., citric acid (CIT), diethylenetriaminepentaacetic acid (DTPA), ethylenediaminetetraacetic acid (EDTA) and pyromellitic acid (PMA), on the crystal growth rate of the calcium carbonate polymorphs aragonite and calcite has been studied. Using a seeded constant supersaturation method supersaturation was(More)
AGA AB ndustrial operators worldwide expend considerable time and money to control the release of volatile organic compounds (VOCs) to the atmosphere. Such emissions react with nitrogen oxides to form photochemical oxidants in I the troposphere. Resulting ground-level ozone or smog causes irreparable damage to crops and has been implicated in forest(More)
The influence of four calcium complexing additives, i.e., citric acid (CIT), diethylenetriaminepentaacetic acid (DTPA), ethylenediaminetetraacetic acid (EDTA) and pyromellitic acid (PMA), and their concentration on the induction time of calcium carbonate nucleation has been studied. The experiments were performed by rapidly mixing a sodium carbonate(More)
