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