Coprecipitation due to surface adsorption can be minimized by the following except: reducing the surface area, i.e precipitating under conditions where more nuclei are formed and small crystals resulted Carrying out a separation of ions that would be strongly adsorbed or replacing it with strongly absorbed ions lowering the oxidation number of metal ions so that it's charge reduced using hot solutions to reduce the amount of adsorption per unit area

Iron nanoparticles were produced by the evaporation method and their average sizes are estimated 25,50, 90 and 120 nm using the laser particle analyzer. Assuming that the resultant particles are strain freeand the peak broadening detected in the measurement with Cu-K radiation (λ=0.154 nm) arises onlyfrom variation of size of the crystallites, estimate the peak width (the value of FWHM) of the (110) plane.
