Published: tue, 25 apr 2017 1 the effect of molecular weight and time on the rate of diffusion of potassium permanganate, potassium dichromate, and methylene blue1 scientific paper submitted in partial fulfillment of the requirements in general. Determine the effect of temperature to the diffusion rate of the compound factors affecting the diffusion rate drop a methylene blue into the test tube. The diffusion of mythelin blue is directly proportional to its concentration, hence as the concentration increases the rate of diffusion increases too controlled variables time time was kept constant while testing the diffusion spread of mythelin blue with each concentration. Phenol and methylene blue adsorption on heat-treated activated carbon: characterization, kinetics, and equilibrium studies diffusion of phenol and methylene blue .
The effects of molecular weight on the rate of diffusion of potassium permanganate and methylene blue a scientific paper presented to the faculty college. Exercise 1 – factors influencing rate of diffusion potassium permanganate rt methylene blue rt time (min) total diameter (mm) distance of diffusion . Osmosis and diffusion abstract: and methylene blue (molecular weight = 374g/mole) at the same time and allow them to diffuse effect of molecular rate on .
Fulltext - prediction of adsorption kinetic rate constant for removal of methylene blue using teak leaf powder. The effect of molecular weight on the diffusion rate of substances - free download as pdf file (pdf), text file (txt) or read online for free methylene blue . Abstract: with anaerobic granular sludge as adsorbent, the adsorption kinetics and thermodynamics of methylene blue (mb) from aqueous solution was studied by batch adsorption techniquethe pseudo-first order, pseudo- second order models and langmuir, freundlich isotherms models were used to describe the kinetic datathe experimental results . The methylene blue which has the largest molecular weight had the slowest average diffusion rate of 002425 mm/min compare to the kmno4 which has the lightest molecular weight had a diffusion rate of 017425 mm/min as obtained in the results of experiment, this satisfies the premise that the higher the molecular weight, the slower.
Particle diffusion, rate of adsorption, isotherms and thermodynamics of methylene blue in 1000cm3 kinetic study of the methylene blue adsorption on white . The effect of molecular weight on the rate of diffusion of potassium permanganate (kmno4), potassium dichromate (k2cr2o7) and methylene blue ¹ abstract the effect of molecular weight on the rate of diffusion was determined using the agar-water gel test. The results of the intraparticle diffusion model suggest that intraparticle diffusion was not the sole rate determining step it was found that the langmuir isotherm model yielded the best for equilibrium data with the maximum monolayer adsorption of 3247 mg/g for methylene blue. The effect of molecular weights on the rate of diffusion sharmaine s bungabong group 1 sec y-7l august 11, 2011 a scientific paper submitted in partial fulfilment of the requirements in general biology i laboratory under prof cristina dorado, 1st sem, 2011-2012 abstract the effect of molecular . One factor that affects the rate of diffusion is the size of diffusing particle in this experiment, three different stains were tested for their speed of diffusion through a colloid the test stains were potassium permanganate, methylene blue, and congo red while the diffusing medium was 5% gelatin solution.
Abstract in this work, the kinetics of diffusion of methylene blue in agar aqueous solution is studied using a photoacoustic technique two agar phantoms solutions in water with a relation of mass/volume of 001% and 005% were analyzed. If molecular weight affects the rate of diffusion, then, the higher or lower the molecular weight the slower or faster the rate of diffusion to test this factor, a drop of potassium dichromate, potassium permanganate, and methylene blue were placed on each wells of the petri dish containing agar water gel. Equilibrium, kinetics, mechanism, and process design for the sorption of methylene blue onto rice husk surface and pore diffusion with surface diffusion at the .
(diffusion rate 2:1) potassium permanganate is half the weight of methylene blue, what does this mean the lighter and smaller the molecule, the faster the diffusion rate. Best answer: according to this site, methylene blue has a higher molecular weight than potassium permanganate therefore smaller, lighter molecules diffuse faster than larger, heavier ones.
Abstract batch kinetic experiments were carried out for the sorption of methylene blue onto activated carbon second-order rate kinetic parameters were examined . The effect of gelatin, glycerin and methylene blue concentration on the diffusion of a dye from gelatin-glycerin-water gels has been examined the rate of diffusion depended on the pore size of the gel and on the viscosity of the interspace fluid. The relationship of molecular weight and rate of diffusion was determined using three colored substances with different molecular weights, namely potassium permanganate, potassium dichromate and methylene blue. Sorption dynamics of methylene blue removal using indian activated coir pith experiments are conducted for discoloration of methylene blue from diffusion rate .
