Modeling and Optimization For H2s Adsorption From Wastewater Using Coconut Shell Based Activated Carbon

Modeling and Optimization For H2s Adsorption From Wastewater Using Coconut Shell Based Activated Carbon

In the current work, the Response Surface Method (RSM) is used to optimize the adsorption efficiency of hydrogen sulfide (H2S) onto the coconut shell activated carbon. The considered design (or operating) variables are; initial H2S concentration, adsorption contact time and adsorbent dosage, while t...
