Absorptivity of Bentonite Clay

Absorptivity of Bentonite Clay Final Project CHEM 112-501 Melissa Cisneros* Danielle Salo The break up of this experiment was to render the absorptivity of Bentonite form, charcoal, and another type of mud. 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 plinth and clamp, thermometer, blue plate, tongs, pipet, spatula, separator tubes, a extractor, 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 water 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 o f 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 come out(a) of the hot water bath and 20 mL of NaOH was added drop-wise. by and by 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 and the leftover clay was suspend in distilled water, then it centrifuged over again and the supernatant once again was disposed of. The clay in the four centrifuge tubes was outback(a) and put in a large beaker that contained the rest of the menages clay. The coterminous week , 40 mg of the clay do by the class, 39.0 m! g of Bentonite clay, and 40 mg of charcoal were apiece 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 in advance it could be transferred to the cuvette. The...If you indispensableness to get a full essay, decree it on our website: OrderEssay.net
