This training examined the adsorption properties of orange peel after treatment with D2EHPA. Preserved examples remained categorized by Fourier Transform Infrared Spectrometer (FTIR) and Scanning Electron Microscope (SEM). The capabilities of adsorptive examples stayed examined through by Cd (II), Zn (II) sorption from these solutions. The numerous investigational factors require remained for example mixed time, concentration of media, RPM, Solid/Liquid ratio besides temperature, require stayed considered then enhanced situations remained resolute by equations. Balance line trainings stayed recycled to calculate the determined adsorption capability of orange peel behavior and the investigational of consequences are presented this Cd (II), Zn (II) about 14.12 and 11.1 mg/g respectively. The consequences displayed that Zn (II) ,Cd (II) adsorption was achieved after 180 min contacting time using (solid/liquid = 8g/L) adsorbent from 30% P2O5 at 25°C. Adsorption rate at pseudo-second order equation, thermodynamic parameters (Δ H°, Δ S° and Δ G°) reveal that the Cd (II), Zn (II) adsorption is calculated.
