In typical measurements, 8 cm downstream of the burner, of species profiles versus λ for a flame doped with type 1 glassy carbon spherical powder, as parts per million, normalized to the Ar36 peak area and the measured particle cross sectional area in Computer Model Study of Carbon Combustion in Low Pressure Laminar H 2+ O 2 Flames. Glassy carbon spherical powder (10-20 μm diameter) modified with cysteine methyl ester is found to be an inexpensive, novel material for the rapid removal of large quantities of toxic heavy metal ions such as Cd(II), Cu(II) and As(III) from aqueous media.
