By Smith, S Takacs, I; Murthy, S; Daigger, G T; Szabo, A ABSTRACT: A phosphate complexation model is developed, in an attempt to understand the mechanistic basis of chemically mediated phosphate removal. The model presented here is based on geochemical reaction modeling techniques and uses known surface reactions possible on hydrous ferric oxide (HFO). The types of surface reactions and their reaction stoichiometry and binding energies (logK values) are taken from literature models of...

By Johnson, Pauline D Girinathannair, Padmanabhan; Ohlinger, Kurt N; Ritchie, Stephen; Teuber, Leah; Kirby, Jason ABSTRACT: The goal of this study was to determine the removal efficiencies of chromium, copper, lead, nickel, and zinc from raw wastewater by chemically enhanced primary treatment (CEPT) and to attain a total suspended solids removal goal of 80%. Operating parameters and chemical doses were optimized by bench-scale tests. Locally obtained raw wastewater samples were spiked with...

By Rohner, Fabian; Ernst, Frank O; Arnold, Myrtha; Hilbe, Monika; Et al Abstract Particle size is a determinant of iron (Fe) absorption from poorly soluble Fe compounds. Decreasing the particle size of metallic Fe and ferric pyrophosphate added to foods increases Fe absorption. The aim of this study was to develop and characterize nanoparticles of FePO^sub 4^ and determine their bioavailability and potential toxicity in rats. Amorphous FePO^sub 4^ nanopowders with spherical structure were...

There are a number of iron oxides: Iron oxides Iron(II) oxide or ferrous oxide (FeO) The black-coloured powder in particular can cause explosions as it readily ignites. Iron(III) oxide or ferric oxide (Fe2O3) known in its natural state as hematite or haematite, but also purified for use as a coating in magnetic audio and computer media, where it is known as ferric oxide. Also known as rouge. Iron(II,III) oxide or ferrous ferric oxide (Fe3O4), better known as the black-coloured...

Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
