Abstract

          Dialium cochinchinensis seed activated carbon (DCS-AC) was prepared for adsorption process. Under characterization, it was found that the iodine number is highest when using H3PO4 was chemical activation reagent in the ratio Char and H3PO4 was 1:1.5, giving the highest iodine adsorption value of 892.91 mg g-1. The SEM image shows that Char has less porosity than DCS-AC/H3PO4 and has an average pore size in mesopore. The DCS-AC/H3PO4 has a specific surface area of 230.96 m2 g-1 which is greater than Char. The highest percentage reactive red 120 sorption on DCS-AC/H3PO4 at equilibrium was 60 %. These results indicated that DCS-AC/H3PO4 could provide an alternative granular adsorbent for the removal dye in wastewater.

QUESTIONS & ANSWERS

รศ.ปัญญา มณีจักร์ (Chairperson)

1.How about the particle size of DSC-Ac in your reaction,we should know.

2.How about the isotherm and mechanical of your meterial adsorption .

Fareeda Hayeeye (Presenter)

Thank you for your questions  

1. The particle size of DSC-AC is 170-200 mesh size.

2. In next step,  we will study isotherm and mechanical part.

Thank you for your presentation.

1. What is the main reason that Dialium Cochinchinensis seed was selected as a sourece of activated carbon production in this study? 

2. What other parameters/factors should we concern in order to furher confirm that the activated carbon produced from Dialium Cochinchinensis seed is suitable for dye removal? 

Fareeda Hayeeye (Presenter)

Thank you for your questions 

1. To produce a low- cost granular activated carbon. Dhialuim Cochichinensis seed which is an local agricultural waste using a simple method for producing activated carbon.

2. The effects of contact time, adsorbent dose and solution pH on the adsorption process should be concern in next step of this research.
