AB  - In recent times, developments in polymer application properties have required the 
      design of different polymer structures more than ever. Cross-linked polymers 
      (CPs) could be considered a good candidate material for potential applications 
      when used in conjunction with nanoparticles. Cross-linked polymethyl methacrylate 
      nanocomposites are considered to be one of the most commonly polymeric adsorbents 
      due to their varied and simple modification methods. A new class of 
      C-PMMA/SnO(2(a-d)) nanocomposites have been fabricated as surface-selective 
      adsorbents of Cr (III) with a good yield and different loading of SnO(2) 
      nanoparticles. The morphology, molecular structures, and thermal stability of the 
      new cross-linked polymers were examined using a Scanning electron microscope 
      (SEM), the Fourier Transform Infrared method (FTIR), X-ray diffraction (XRD), and 
      Thermogravimetric Analysis (TGA). The adsorption study of C-PMMA/SnO(2) was 
      investigated, and an efficient level of adsorption for Cr (III) cations was 
      detected. To evaluate the potential for the new polymers to be used as adsorbents 
      against Cr (III) ions, the contact time, the initial concentration of Cr (III), 
      and the effects of pH were studied. The introduction of SnO(2) into the polymer 
      network enhanced the efficiency of the adsorption of heavy metals. The 
      C-PMMA/SnO(2) is highly efficient at removing Cr (III) ions in wastewater samples 
      at pH 6 for one hour. The adsorption study demonstrated that the adsorption 
      capacity of C-PMMA/SnO(2)c for Cr (III) was 1.76 mg /g, and its adsorption 
      isotherm agreed with the Langmuir adsorption model.
