Süzdüğüm AR çözeltisine nitrik öldükten sonra demir sülfat ekledim, çözelti rengi çok koyu oldu, ancak metaller askıda kaldı. Sebep nedir, ne yapmalıyım. Şimdiden teşekkürler
 
Çözeltiyi kalay klorür ile test ettiniz mi? Değilse, solüsyonda hala altın olduğundan emin olmak için test edin.

So please continue in English.
 
Hello Erol,
Why you use iron sulphate,
its very old method you can use different percipitants.

Also, if you think there is still metal in solution after you filtered out, you can test it.
After testing it, you can add more precipitants or after additional urea you can add more percipitant.

It happens when urea not enough or nitric is too much added. Be careful my friend.
