Is Silica help to adsorp heavy metal from aqueous solution?
(OP)
Hi all,
My biomaterial contains high percentage of Silica and Calcium element in its biomass. I am now utilizing this biomass for the heavy metal removal from aqueous solution and the result was very satisfactory. My question is that does silica or calcium have any function to the removal of heavy metal from aqueous solution? what are their mechanism? As i know Silica and calcium are one of the metal, so i guess that those silica in the biomass should be present in a complex form not a single element like SiO4, Ca(OH)2, or something similar to this.
Anyone know if there are any relation between these elements with the adsorption capacity of my biomass?
Best regards all,
LPY2000

If you are taking readings at time intervals, you may be able to use Ca, Na, and K as your indicators. If they increase over time, you can assume ion exchange is occuring, until your exchange capacity is exhausted.
