Activated carbons are applied in separation and purificationtechnologies, catalytic processes, biomedical developments, pollutioncontrol, and energy storage, among other usages (TreviñoCorderoet al., 2013). Activated carbons, because of their largesurface area and relatively high adsorption capacity for a widevariety of dyes, have become the most promising and effectivelyadsorbent (Yang and Qui, 2010). Activated carbon can be producedfrom any carbonaceous solid precursor, which is largely dependenton its availability, cost and purity. Activated carbon is the mostwidely used adsorbent for the removal of dyestuff fromwastewater because it has an excellent high surface area and highadsorption capacity for organic compounds, but its use is usuallylimited due to its high cost (Karagozoglu et al., 2007). For thisreason, many researchers have investigated more cheaper and effi-cient activated carbons for the removal of dyes from wastewater such as rice husks (Lin et al., 2013), sugar beet bagasse (Demiral and Gündüzog˘lu, 2010), wood sawdust (Foo and Hameed,2012a), walnut shells (Yang and Qui, 2010), cashew nut shell (Senthil Kumar et al., 2010), and plum kernel (Treviño-Corderoet al., 2013).Due to environmental consideration, agricultural and foodindustries’ wastes are considered to be very important precursorbecause they are cheap, renewable, safe, available at large quantitiesand easily accusable sources (Ahmed and Theydan, 2012).
These residues are usually disposed of by burning or by deposition
in landfills, but conversion to higher-value products such as activated
carbon would be preferable. Processing of fruits produces a
solid waste of peel/skin, stones or seeds which can be used as precursor
for the production of activated carbon. There are lots of
fruits containing considerable amounts of stones. One of these
fruits is sour cherry (Prunus cerasus L.). Turkey is the largest producer
of sour cherry in the world with an annual production of
192,705 tones (Damar and Eksi, 2012). In present study, adsorption
characteristics of high surface area activated carbon (Angin, 2014)
obtained from sour cherry stones were demonstrated for the
removal of dyestuff which is Yellow 18.
