EVALUATION OF PISTACHIONUT SHELLDERIVED ACTIVATED CARBONASANADSORBENTFOR UPTAKE OF DIFFERENTDIBASICACIDS

Abstract

In this study, adsorption of different dibasic acids was performed on pistachio shell carbon,which was used as an adsorbent, asit is serves as eco-friendly adsorbents. It has proven to be significantly effective with the provision of satisfactory adsorption capacities for the removal of pollutants from waste water. We have studied adsorption on different dibasic acid by taking pistachio shell carbon as an adsorbent. The dibasic acids under study were oxalic acid, malonic acid, succinic acid and Glutaric acid.Pistachionutshellisthebestmaterialthatcanbemadeintocarbonasthey have a lot of micropores, low ash content high water Solubility and high reactivity.Pistachio nut shell carbon has become one of the best forms of carbon for waterfiltration and water Purification in recent years. Additionally, it can effectively absorbCertainimpurities. Inthevery firststepwecollectpistachionutshellandremoveddirtandunwanted substances from it. Then the shell is smashed and crushed and put it in acontainer or furnace and get it for heating. The heating is done until the pistachio nutshell by product it is the pistachio nut shell processed into carbonation of the latter toproduce pistachio nut shell carbon in the form of burned carbon. In the run of burningof pistachio nut shell, the heating temperature should be programmed to increase fromthe room temperature to the desired carbonization temperature. The overall preparationis bychemical method. The adsorption isotherm for Langmuir adsorption isotherm and Freundlich adsorption isotherm was studied for different dibasic acids by taking pistachio shell carbon as an adsorbent. The results obtained when compared with different acids the conclusion obtained was compared with differentdibasic acids (oxalic acid, malonic acid, succinic acid and glutaric acid).Fromthereadingsobtainedit wasobservedthatextentofadsorptionof oxalic acid (0.01182), malonic acid(0.01166), succinic acid (0.01263) and glutaric acid (0.01221)reasonbehindtheaboveconclusionmay bethepresenceofCH2group. theextentofadsorptionof,succinicacid(0.01263)>oxalicacid(0.01182)thereasonbehindtheaboveconclusionisthepresenceof2CH2groupinsuccinicacid or absenceof2 CH2groupin oxalicacid.
