Results and Discussion
Results of scolecite were shown in Tables 1 and 2, the chemical composition of the natural zeolite as oxides. SiO2 and AL2O3 percentage were found high in sample. This indicates that silicate and aluminate are important components in natural zeolites. Percentages of metal oxides (Fe2O3+, CaO+, MgO+, Na2O+, K2O) were found (32.31%) and this indicates that all cations were exchanged by Na+ ions to form sodium zeolite as cation exchanger. The exchange of multivalent metalions can be achieved in low pH to ensure the solubility of heavy metal cations according to Blanchard [11]. Characteristics of Scolecite were drown in Figures 1-3. The identification of the zeolite was carried by X-Ray diffract meter (XRD), system: Philips, Model: X-pert PRO stress XRD analyzer Cu-target radiation, used in the present work phase analysis was achieved by using XRD, sample was analyzed and found to be scolecite Figure 1. SEM photograph of zeolite particles is shown in Figure 2. It is clear that particles are rectangular in shape with sharp edges. In the infrared spectrum shown in Figure 3 of Scolecite without chemical processing but grinding as powder. It is reported the following positions of these bands: 462.88 cm-1 bending [O-Si(Al) O+ Si-O-Al], 1029.9288 cm-1 stretching [Si(Al) O], 1645.17cm-1 [O-O] bond of water molecules bending (OH), and around 3423.41 cm-1 region stretching (OH).
