humic acid silica sand

Humic acid-, ferrihydrite-, and aluminosilicate-coated ...

Feb 01, 2006  The amount of humic acid that we could coat onto the sand was around 1 mg/g of sand (), which is similar to the result obtained using sol-gel immobilization .Koopal et al. reported a surface coverage of humic acid of 56 mg/g, but used a much smaller-sized silica support than we did. On a per surface area basis, our 26 mg/m 2 compares with 1.1 mg/m 2 from Koopal et al. .
