Seaweed Drinks

Seaweed Drinks, a revolution for humanity !

This year, we worked hard and we tried to find a way to use seaweed in our diet.
So we used column chromatography and thin-layer chromatography to separate components of Spirulina and prove it contains more beneficial components than Spinach.
With the different components we collected, we tried to introduce in each test tubes a specie wich show the presence of iron in spirulina. But the test failed.
We did so a dosage by calibration of different solutions of different concentration of Iron.
With the Beer Lambert's law, wich states the coloration of a solution contain a colored specie is proportional to the concentration of this specie.
But we meet some problems like malfunctioning equipment or not much diluted solution of Irons etc..
We did finally some research on the Internet and we find different countries which use

Our project is about Orange Juice.




We have make experiment with this orange juice.

 Our leading question is "Why you have to drink quickly an orange juice?"

Our experiments:

-chromatography of sucars

-dosage of glucose

 -dosage vitamine C

 -recuperation and dosage of ethanol























Our projet

TapWater: Titration with EDTA 

       The goal of this titrationwith EDTA is to detect the presence of ion calcium in tapwater. To prove this presence of this ion you must to put on a becker tapwater with indicator and over this becker you put on the buret a solution of EDTA. EDTA react with the ion calcium and the indicator. With the volume equivalent you can calcul the concentration of ion calcium in the tap water.

Make a sound with a light









In this experiment we have made a sound with a light.
We capted the light with a photodiode and we transmite it to a speaker.
 this system is like a wireless system




Project : Biofuels

 Extraction of the oil from sunflower's seeds.

Andony Gatinaud Barberteguy, Vincent Mirailh and Thibaut Latapy are going to talk about an experiment of our project. This experiment consists in extract the oil from the sunflower's seeds.
We have mix 30g of sunflower's seeds with 10mL of cyclohexane. The cyclohexane has the role of solvent in order to extract the linoleic acid contained on the seeds. At the end of this experiment, it stays only cyclohexane and linoleic acid.
