Phosphate and thermal stabilization of heavy metals in dredged sediments
… leachability of metal contaminants subsequent to phosphate addition and thermal treatment at 700 C. X- ray absorption spectroscopy (XAS) in combination with principal component analysis, target transformation, and linear combination revealed that in the untreated sediments Zn precipitated as the …

Sorption of Metals onto Natural Sediments and Engineered Iron Oxide Nanoparticles
… contamination in subsurface environments, phosphate addition has been performed for in-situ immobilization, which can avoid the costs associated with pump-and-treat or excavation-based remediation strategies. The interactions of uranium and phosphate in Hanford sediments had been …

Geochemical Conditions Affecting Uranium(VI) Fate And Transport In Soil And Groundwater In The Presence Of Phosphate
… like uranium is a serious environmental concern. Phosphate addition to uranium-contaminated soil and groundwater can potentially provide long-term in-situ U(VI) immobilization by precipitation of low solubility U(VI)-phosphates. Reactions at the iron: oxy)hydroxide-water interface can control …

An exploratory investigation of the possibility for electrodepositing aluminum from miscellaneous organic system
… tests with the system aluminum stearate-ethyl phosphate-addition compounds. The addition of 0.4 gram of stearic acid and 0.8 gram of lithium stearate to a bath of 0.2 gram of aluminum stearate in 74.6 grams of ethyl phosphate resulted in the greatest increase in current obtained with any of the …

Effects of Scale Reduction Technologies and Chemical Inhibitors on Calcium Precipitation in Premise Plumbing Systems
… media induced precipitation, sacrificial media (phosphate), and sacrificial media (citric acid). While calcium carbonate precipitation within a water distribution system is generally undesirable; it was recently discovered that calcium carbonate particles are sometimes naturally clogging leaks in …
