Kinetic modeling of AS(III) and AS(V) adsorption by a novel tetravalent manganese feroxyhyte.

摘要: Abstract Hypothesis The purpose of the present work is development a kinetic model for adsorption As(III) and As(V) onto tetravalent manganese feroxyhyte (δ-Fe 0.75 Mn 0.25 OOH), which have been recently proved to be very efficient adsorbent particular species. Experiments In this respect equilibrium experiments type were performed. Two sizes adsorbate particles are tested in order acquire better insight process. Results curves cannot described by well-known models so detailed that takes into account structure particle developed. parameters extracted requirement agreement between experimental results. batch developed here necessary fixed bed devices exploit commercial prospects adsorbent. This constitutes first attempt study specific promising
