Introduction Filtration is a unit operation that separates liquid from a suspension with the use of a porous medium (Coulson & Richardson, 2002). Filtration. 1 FILTRATION OBJECTIVE : • To study the theory of filtration • To determine the average cake resistance for the given slurry and the resistance of the filter medium used in the filtration process. Distribute lab supplies to each station (2-liter soda bottle pre-cut in half, filtration materials, "pollution" materials). Lab Station #2 Lab Partner: John February 13, 2014 Experiment #1 Photoelectric Effect February 13, 2014 Photoelectric Effect Objective In this lab, students will observe the line spectrum emitted by a mercury vapor lamp. The Butterworth filter is also called a maximally flat or flat-flat filter, and all filter in this experiment will be of the Butterworth type. This proves my hypothesis right. Continuous Filtration 1. I Experiment 2 Separation Of Mixtures INTRODUCTION A mixture can simply be defined as a substance that is made up or consists of two or more elements and/or compounds that are physically combined but that have not reacted chemically to form new substances. The purpose of the experiment was to separate an initial heterogeneous mixture composed of 5.00 grams of salt, 2.00 grams of sand, 50.0 mL of water, 15.00 grams of pebbles, and 1.00 gram of iron filings, and leave as much salt as possible remaining. CHROMATOGRAPHY: FRACTION COLLECTION 1. It depends on what they are designed for and if they . Experiment 1 was effects of groundwater contamination. 1) They can improve the quality of water. Chilled crystals in ice bath for 19 minutes. The contaminants used in the experiment are the most common . We then built our filter bottom up, starting with a rubber banding a coffee filter to the bottom as a final catch-all for the finest particles. THIS PROBLEM MUST BE ANSWERED IN YOUR LAB REPORT AND WILL BE GRADED. Experiment 3: Reverse-phase Chromatography 1.

Large proteins are confined to V o and small proteins occupy and elute with V t . 2. Lab Report. Equilibrate the column by washing with 2-3 syringe volumes of water. . Experiment A low pass filter was constructed on a breadboard and instrumented as shown in Figure 2. Wash the column by injecting the alcohol through the column. The purpose of the experiment was to separate an initial heterogeneous mixture composed of 5.00 grams of salt, 2.00 grams of sand, 50.0 mL of water, 15.00 grams of pebbles, and 1.00 gram of iron filings, and leave as much salt as possible remaining. Add one drop of ink or food colouring to 100 cm 3 of water in a beaker. Filtration The Plate-and-Frame Filter Press A laboratory report submitted to Luis K. Cabatingan CHE 512L Instructor by Serge Lorenz Villasica October 5, 2015 f1. The slurry is the suspension from which the liquid is to be separated through a filter medium. In this experiment, gravity creates the pressure needed to push some particles across a paper membrane. stopwatch or timer DIY Water Filtration System for Science Project Pour swamp water in the 2-liter bottle with a lid. Discussion: the water filtration process dropped the turbidity . According to the results of this experiment, the pH of the potatoes themselves, pH6, was the optimum pH for the catalase to work. The solution of liquid and sold is decanted through the filter paper in the funnel. Conclusion. Synthesis Of 4-Nitrobromobenzene Lab Report The para product was expected to have the higher yield, since it is more stable and consequently harder to break down throughout the experiment. The solution was cooled and a vacuum filtration was done to remove the caffeine crystals. 2. This involved a 3-step synthesis over the course of 3 weeks. 38 ml total solvent volume. Give the background information on your experiment explaining . If necessary, another piece of filter paper can be used. Combining different materials to create a filter is one way to clean dirty water. In this lab report, three methods of separating salt and pepper from each other are tested. carbon filtration experiment (from left to right: 0 drops per cup of liquid, 2 drops per cup of liquid and 5 drops per cup of liquid). most commonly used form of HPLC. After the ten minutes are over, throw out the hot water and ice and place your Petri dishes back. Experiment 5 Gel Filtration Abstract Blue dextran, cytochrome c, and K2CrO4 were separated by size using size exclusion chromatography. This charcoal water purifying experiment is a great experiment for middle school students to try on their own. Aspirin Lab Report Introduction The objective How Filtration is a process used to separate solids from liquids or gases using a filter medium that allows the fluid to pass through but not the solid. RC Filter Networks Lab Report Robert Clancy 04329741 December 8, 2005 Abstract The aims of this experiment are to examine RC circuits as low-pass and high-pass lters to source voltages of sinusoidal and square wave signals. Fill the syringe with 35% isopropyl alcohol and attach the syringe to the column. (one for each student, or one for each lab group) and Worksheet #2 - Water Filter Lab Worksheet (one for each student). 8. Filtration is commonly the mechanical or physical operation which is used for the separation of solids from fluids (liquids or gases) by interposing a medium through which only the fluid can pass. If desired, the experiment can be extended to isolate dry samples of sand and salt. your lab report Experiment 4: Introdudion to Separation Techniques part The Objecfives Of the lab are to learn how different substances can be separated using two filtration techniques for heterogeneous mixtures.
