Abstract

1. INTRODUCTION Clean water is requirement for all. Methylene blue is one of the most commonly used substances in the textile industry. Methylene blue can damage the balance of the ecosystem and adversely affect the environment [1–3]. The methylene blue compound is very easy to obtain because its cheap price and wide use in dyeing process [4]. The dye molecule is very stable, thus difficult to be decomposed under natural conditions. Therefore, it is necessary to remove the dye molecule before being discharged to the environment [5]. The removal technique of dyestuff has been widely studied including ion exchange, membrane filtration, coagulation-flocculation, flotation, electrochemical processes, reverse osmosis and adsorption [6–8]. But due to various advantages and disadvantages adsorption has been given the prime importance and is frequently used [9]. Table 1 depicts the merits and demerits of other technologies for dye removal from water [10]. The adsorption method is recognized as a relatively simple and an effective method [5,11]. For adsorption process various commercially available activated carbon is the most widely used adsorbent for dye removal, but they are too expensive. Therefore, numerous low-cost alternative adsorbents from have been proposed including chemically modified sugarcane, lignin, pistachio hull waste, coffee husk-based activated carbon, pine cone, rice husk, synthetic calcium phosphates, natural untreated clay, pillared clays and swelling clays, Lantana, peanut hull [12].
