Removal of Methyl Red using Chemical Impregnated Activated Carbon Prepared from Parkia speciosa Pod (Petai) as a Potential Adsorbent

Abstract

Textile industry is one of the major contributors either in terms of employment or economies.This industry has provided variety of daily necessity such as sources of yarn and clothing.Extensively use of dyes in this textile industry has created water pollution. The serious problemhappened when the daily water usage is from the untreated effluents which are discharged directlyinto water bodies. However, the disposed dyes into environment can be treated with adsorbentssuch as activated carbon via adsorption process. In this study, Parkia speciosa (petai) pods werechosen as the raw material from agricultural waste to produce activated carbon. Activated carbonwas prepared from two different chemicals and application of four different carbonization time.Two parameters studied in the experiment are initial dye concentration and contact time. From theresult, 100% of methyl red was removed by the activated carbon impregnated with zinc chloridesolution at 1 hour carbonization time. The optimum time and initial concentration of dye was 30minutes and 10 ppm respectively with the percentage removal of 100%. Thus, this result couldcontribute some knowledge on the use of alternative adsorbent from agricultural wasteimpregnation with specified chemicals in treating textile industrial wastewater.

Efficient Removal of Methyl Red Dye by Using Bark of Hopbush

“…It also shows that not all adsorption sites are homogenous, suggesting that multilayer adsorption may take place on the surface of the adsorbent. Table 3 shows a comparison of D. viscosa plant bark powder's ability to adsorb MR dye with that of other inexpensive adsorbents from earlier studies [58][59][60]. It was discovered through this comparison that utilizing 100 mg of adsorbent per 10 mL of solution MR dye (500 ppm and at pH-1) during a contact time of 75 min offers outstanding results.…”

Methylene Blue Removal Using Foxtail Palm Fruits as Potential Activated Carbon

“…However, the consumption of commercial activated carbon is costly due to its production. Hence, production of activated carbon from agricultural waste or unwanted part of the plant is necessary in order to reduce the production cost furthermore it can be one of the environment sustainable solutions for the disposal issue [4]. Due to the abundance of foxtail palm fruit in Malaysia, as its trees are planted most along the road as an ornamental plant, the fruits were chosen as a potential raw material for the activated carbon production and expected to have the ability for dye removal.…”

“…Due to the abundance of foxtail palm fruit in Malaysia, as its trees are planted most along the road as an ornamental plant, the fruits were chosen as a potential raw material for the activated carbon production and expected to have the ability for dye removal. Previously, a lot of studies have been conducted on using various agricultural wastes such as pea shell, pineapple (core, peel and crown), parkia speciosa pod, kenaf and rubber wood sawdust [2][3][4][5][6]. Hence, in this study foxtail palm fruit was used as the new and potential raw material for the activated carbon production to be further used to treat dye pollution.…”
