Absorptivity of Bentonite Clay

Absorptivity of Bentonite Clay Final Project CHEM 112-501 Melissa Cisneros* Danielle Salo The drive of this experiment was to render the absorptivity of Bentonite form, charcoal, and another type of dust. Bentonite clay as nearly as charcoal can be used as a means of removing pollutants such as Polycyclic Aromatic Hydrocarbons (PAHs) from irrigate sources. Materials and Methods: Materials used in this experiment were 600 mL beaker, 250 mL Erlenmeyer flaskful, 50 mL graduated cylinder, ring project and clamp, thermometer, blue plate, tongs, pipet, spatula, separator tubes, a centrifugate, cuvettes, and a spectrop piquantometer. Chemicals used were FeCl3 Anhydrous, FeSO4- ? 7H2O, Bentonite clay, 2.5 M NaOH solution, and Procion Red MX-5. To leave the clay, 250 mL of distilled pissing was heated in a 600 mL beaker to 70° to be used as a hot water bath for the Erlenmeyer flask. 40 mL of distilled water was added to the flask along with .80 g of FeCl3, .40 g of FeSO4-, and .30 g of Bentonite. Using tongs, the flask was stirred in the hot water bath to scatter the iron compounds and the clay. The flask was because taken appear of the hot water bath and 20 mL of NaOH was added drop-wise. later on it was the right way cooled, the solution was equally distributed to four centrifuge tubes and centrifuged for 5 minutes.

The supported was poured out(p) and the leftover clay was suspend in distilled water, then it centrifuged again and the supernatant once again was disposed of. The clay in the four centrifuge tubes was aloof and put in a large beaker that contained the rest of t he crystallises clay. The coterminous we! ek, 40 mg of the clay make by the class, 39.0 mg of Bentonite clay, and 40 mg of charcoal were separately added to a centrifuge tube along with 15 mL of Procion Red spot and shaken. The tubes were centrifuged for 2 minutes, then taken out and transferred to cuvettes using a pipet. The solution with Bentonite clay had to be filtered forward it could be transferred to the cuvette.
