2.3. Membranes and modules for forward osmosis: 2.3.1. FO Membranes Generally‚ any dense‚ non-porous‚ selectively permeable material can be used as a membrane for FO. Such membranes have been tested (in flat sheet and capillary configurations) in the past for various applications of FO. In early studies‚ the researchers applied various FO membrane materials‚ including bladders of pigs‚ cattle‚ and fish; collodion (nitrocellulose); rubber; porcelain; and goldbeaters’ skin [36]. By 1960‚ Loeb and

Introduction: The purpose of experiment 1 was to demonstrate the principle of simple diffusion and understand how to make % solutions. Exercise 2 demonstrated the principle of osmosis: observing the movement of water by osmosis from an area of lower concentration of a solute to an area of higher concentration of a solute. Materials and Method: Refer to pages 47-51 of Bio 203L Lab Manual. Results/ Discussion: The effect of the chloride ion on its rate of diffusion in agar means it will diffuse

Michelle Yeung Bio 101 Cyrus MacFoy June 16‚2015 Diffusion and Osmosis Exercise I. Molecules are always in constant movement. Molecular motion is a form of energy‚ the kinetic energy of molecules. The Brownian movement is the movement of small particles caused by the bombardment of the particles by millions of water molecule. This movement will continue indefinitely as long as there is water. My prediction for this lab is the solution of the water is hypertonic meaning there is a higher concentration

Diffusion and Osmosis Shown In Solutions Section 1: Abstract This lab‚ title Diffusion and Osmosis‚ was centered around the diffusion across a cellular membrane and how exactly materials move and diffuse in concentrations. Both diffusion and osmosis are forms of movement that are part of passive transport dealing with cell membranes. Diffusion is where the solutes move from an area of high concentration to a low concentration. Water goes through the cell membranes by diffusion. Osmosis is specifically

Investigation of Factors Affect Osmosis in Potatoes Aim The aim of the following experiment was to investigate the effect of varying the concentration of sucrose solution on osmosis in a potato. Preliminary Experiments One preliminary experiment was done before the main experiment. From the preliminary‚ we were trying to find out how osmosis actually occurred in potatoes‚ and gave us a vague idea on what the main experiment would be like. This preliminary will aid my prediction

1. Diffusion and Osmosis‚ June 4‚ 2013 2. Purpose: The purpose of this lab is to help give visual understanding of diffusion which is a solution of high concentration spontaneously (no energy required) moving to an area of low concentration. Also taking a look at osmosis‚ which is the movement of chemicals across the cell membrane. Osmosis requires some type of energy to be put in for this to happen. After these experiments we should have a better idea and visualization of how chemicals transfer
