Ochre (Ocher)refer to several forms of octahedral iron oxide namely hematite –Fe2o3 and goethite –FeOOH it is a type of clay stained with coloring minerals found in natural deposits in many different regions of the world this investigation presented here focused on the transformation of red ochre into an iron –rich powder as a coagulant to remove the acid red 151 in aqueous solution to achieve this purpose ochre was treated in sulfuric acid and water the treatment capability of this new coagulant was determined by investigation of the dye removal efficiency response surface mehodology was used to study the effect of the various parameters including initial pH 2 milliequivalent of sulfuric acid per gram of ochre used in preparation of coagulant 3 initial dye concentration and 4 coagulant dosage to optimize the process conditions for the decolorization of acid red 151 solution.<\div>

Nanoparticles of MIL–88B(Fe), a metal organic framework material has been synthesized in a functional ionic liquid (FIL) {[CH2CH2] O2 (mm)2} medium under ultrasound condition. The particle size of these structures was 80 nm. The spindle–shape crystal of MIL–88B (Fe) with length about 2 μm and diameter about 1 micrometer, also prepared by ultrasound method when the functional ionic liquid (FIL) {[CH2CH2] O2 (mm)2} was not in the synthesis medium. The preparation of various structures of MIL–88B (Fe) was proved by xrd spectra and SEM images. MIL–88B (Fe) was synthesized in the presence of ionic liquid and in the absence of it, the particle size and morphology of MIL–88B (Fe) change by using of ionic liquid in synthesis medium.<\div>
