Philippe,
Read the "procedure for making ferric oxalate "
Change "200 g.of ferric ammonium sulfate" in "25 g. FeCl3 (or 40 g. FeCl3.6 H2O)"
Change "Add 100 ml of strong ammonium hydroxyde" in "add ammonia"
Change "now take a 1 foot.....etc..." in " use a coffee-filter holder with a coffee-filter"

and make your own FO with the" Sullivan method"

Erich.

Erich,

 

Thank you it is very intéressant

 

Are you possible to describe the process with a little texte with the quantité of chemical

 

2 FeCl3 + 6 NH4OH --> 2 Fe(OH)3 + 6 NH4Cl

2 Fe(OH)3 + 3 H2C2O4  --->  Fe2(C2O4)3 + 6 H2O

 162 g. FeCl3 --> 107 g. Fe(OH)3

                                     107 g. Fe(OH)3 needs 87 g. H2C2O4

25 g. FeCl3 =  40 g. FeCl3.6 H2O

 

Thank you it is very interesting but I did not understand everything Know you write the successive stages with chemicals and quantities of chemicals
Thank you for your help

 

Philippe
