The charcoal does not stimulate efficiency in absorbing metals have higher carbon that is triggered by acid with standard deviation increased to 15.52 and 32 for Pb and Cd uptake, respectively.
Charcoal is not motivated to show the efficiency of adsorption is higher than coal induced by acid. , with standard deviation increased to 15.52 and 32 for the adsorption Pb and Cd, respectively.
Charcoal does not stimulate the performance of adsorption than charcoal activated by acid โดย has standard deviation increase to 15.52 32 and for the adsorption and Pb Cd. Respectively.
