Can you determine silicon content using ICP-AES?

Hello researchers Is this a random laser or just fluorescence?

I am using Rhodamine6G as gain medium and silver nanoparticles as scatterers on a microscope slide and laser input 532 nm comes from above.

In the presence of VERY high concentration (1000 ppm) of silicon, the adsorption isotherms of arsenic are showing anomalous trends, why so?

I conducted an adsorption experiment of arsenic on soil in the presence of different doses of silicon as competing ions to see the effect of silicon on arsenic adsorption and desorption. I took 5...

Hi Kamyar,

thanks for the response. Do you have any papers detailing these procedures and what is the third method that you are talking about?

Lin Zeng

Hi, you can dissove the composite with silica in a solution and then can analyze the silica content with ICP-AES.

Dimitar P. Mitev

Hi,

In some cases even direct evaluation of nano-suspensions is reliable:
