Making Fe3O4 Magnetic nanoparticles | How to make Iron Oxide magnetite Nanoparticles 

Sr I have tried your method and it worked well, but I used 4.7g of FeCl3.6H2O and 4.0 of Fe2SO4.7H2O then i titrated with 6M NH4OH drop wise. then it takes 40 min to obtain FE3O4 naniparticles. Thank you

Please have you an article about this?

I uses electrolysis with 70 degrees centigrade caustic soda solution with iron as +electrode

Can you please tell me how long is the reaction time

Nice Video

Super! Thank you very much!

merhabalar, fecl3ve fe2(so4).7h20 nun net rakamlarını yazı olarak yazabilirmisiniz. ilk etapta bunları suda çözdükten sonra nh4oh ı ne kadarlık seyreltik damla damla ekliyorunuz ben tam olarak anlayamadım video da. teşekkürler

This method doesn’t need nittogen bubling?

Hocam merhabalar, Fe304'ü Türkiye'de bulabiliyor muyuz hazır olarak yoksa labda ayrıca hazırlamamız gerkeiyor mu? lisans öğrencisiyim bioadsorbentleri magnetize etmek için kullanmam gerekecek. İyi çalışmalar dilerim.

sir, thank you for the video i need your helps, i have 2 questions for you 1. how many degrees Celsius do u strir it? 2. do you store it in a nitrogen atmospheres? because Fe3O4 particles are easily oxidized in air condition. I hope your respone, many thanks, sir

For producing magnetic hydrogel can we directly add hydrogel to this nanoparticle solution ?

Can we perform this same experiment by reducing the weight of the reagents proportionally???

ugh *Clutches chest* the fact that you used anhydrous Iron(III) chloride to make an aqueous solution irks my soul.

hi can you list what instrument and apparatus that you used. Thank you

please sir make a video about making alfa Feooh.

Can u please share the article or give me some suggestion how to Agno3 incorporate into hydrogel??

hello sir, Thank you for this video, Can you please tell me how you dry magnetic nanoparticles?..... Can we dry these nanoparticles at 60 degree Celcius?

what are the reaction parameters, at what temperature have you used?

How much (volume) Ammonium Hydroxide solution was used? What was the molarity of Ammonium hydroxide solution? When did you stop adding Ammonium Hydroxide? What if we use green leaf extract instead of water?

Can you please tell me about procedure in written form or any article?

I which solvent you make the solution?@H2O ?

Kindly tell the ratio of ammonium hydroxide with distilled water, thanks

Hello brother I have chosen fecl3.6h20 and Fecl2.4H2O and Nh3 using 1:2 ratio and dissolved in 60 ml distilled water but I got xrd values for Fe2O3 not for fe3o4 nanoparticles, wat can I do brother plz tell me any suggestion. Thank you

Hello, I have tried synthesizing magnetite using the method you have shown in this video. However, I did not add the ammonia hydroxide drop wise, I immediately added it. Upon vigorous stirring, the ppt became black and I left the solution to settle. I then tested it with a magnet and they were magnetite ppt. My question: Since I added the NH4OH immediately, is there any chance that the ppt are pre-mature? I want to use the ppt as pigment and for some reason I am unable to get the desired quality.

did ammonium hydroxide can be replace by only naoh?

hello i want know it is one step method or two step method. thank you

Excuse me, if we use NaOH. How many concentration do we need?

sorry; I didn't understand,how much fe(II) and fe(III)?

What was the molarity of FeCl3 and FeSo4 solutions?

Hi... thanks for the video... i had tried the same method. On adding NaOH solution, at one point the reaction mixture started to get very thick indicating the formation of magnetite nanoparticles. Can we stop adding the reducing agent then? or do we have to continue adding the same?I used 0.2M FeCl2.6H20, 0.4 M FeCl3.6H20 and 3M NAOH solution...

Have u not used heat of 80°during the precipitation reaction

What is the size should be?

can this be used to remove phosphates from water

Hi sir.... I have tried this method. After addition of NAOH and continuous stirring. I moved up a magnet over the sides the beaker ,the particles haven't risen up.... I am not sure about the amount and concentration of added NAOH...What might happened? can you pls tell sir...

Is not necessary to perform this experiment under nitrogen?

Hello brother which compound r u using in tis synthesis

how much ammonia consumed..

Please check the amount of the agent. the FeCl3 should not be 9.4g to keep the Fe3+/Fe2+ =2 to form Fe3O4?

Which method use sir

sir please send the research paper of this experiment......

how to make this Fe3O4 have spike?
