Mechanisms of lead, copper, and zinc retention by phosphate rock.
The solid-liquid interface reaction between phosphate rock (PR) and metals (Pb, Cu, and Zn) was studied. Phosphate rock has the highest affinity for Pb, followed by Cu and Zn, with sorption capacities of 138, 114, and 83.2 mmol/kg PR, respectively. In the Pb-Cu-Zn ternary system, competitive metal sorption occurred with sorption capacity reduction of 15.2%, 48.3%, and 75.6% for Pb, Cu, and Zn, ...
متن کاملThe concentration of Lead, Cadmium, Zinc and Copper in sediments of Ganduman wetland with geochemical indices
Sediments play an effective role in pollution control or water purification of the wetland ecosystem and record heavy metals contamination as an historical archive. Ganduman wetland is one of the top 10 birdwatching wetlands in Iran. This study aimed to to investigate the concentration of lead, cadmium, copper and zinc in Ganduman sediments. For this purpose, sediment samples were collected man...
متن کاملSimultaneous determination of lead, cadmium, copper and zinc in Infant formula by anodic stripping voltammetry
Determination of trace elements in food is of great importance, as some of them have nutritional significance, whilst others are toxic. Long-term exposure to low levels of toxic metals could be important, especially in relation to children. Differential Pulse Anodic Stripping Voltammetry (DPASV) is applied to simultaneous determination of lead, cadmium, copper and zinc in dry ash infant formula...
متن کاملWater quality improvement through bioretention: lead, copper, and zinc removal.
Intensive automobile use, weathering of building materials, and atmospheric deposition contribute lead, copper, zinc, and other heavy metals to urban and roadway runoff. Bioretention is a low-impact-development best management practice that has the potential to improve stormwater quality from developed areas. The practice represents a soil, sand, organic matter, and vegetation-based storage and...
