Abstract The pollution caused by industrial waste has become a major problem for most of the countries. The present paper deals with the effect of activated carbon and fly ash on removal of acid magenta dye from aqueous solution under different experimental conditions such as exposure time, pH, temperature, and different amount of adsorbent. Maximum 85% and 91% acid magenta dye (20 ppm) removal was observed at low pH (pH 2) with activated carbon and fly ash treated dye solution, respectively. The phytotoxicity study exhibited that Vigna radiata seeds showed better response in the fly ash treated dye solution in comparison with the R. T.

activated carbon. The results revealed that fly ash, one of the industrial wastes, can be used as low-cost and effective adsorbent for the removal of acid magenta dye from aqueous solution. Keywords Acid magenta, Activated carbon, Fly ash, Wastewater treatment
1 Introduction Water, food, and energy are the three main components which ensure human survival. The access to adequate power supply is essential for socioeconomic development of a country. In India, approximately 70% electricity is generated through the coal-based thermal power plants. According to Jambhulkar et al. [1], coal fly ash is produced in India approximately 120 million tons/year from more than 85 thermal power plants which may increase to 442 million tons/year by the year 2035. The management of huge quantity of fly ash is a challenging task for thermal power plant. Fly ash is used as a supplementary material in the production of cement [2], aerated concrete [3], clay bricks [4], etc. It can also be used as an agricultural fertilizer and soil conditioner due to its high water retention capacity [5]. Although the use of fly ash has been significantly increased from 8 to 70% from 1997 to 2010, still approximately 40% of the fly ash remain unused [6]. Fly ash pollutes water resources and soil if it is directly dumped into the environment [7]. Fly ash contains many heavy metals and trace elements which enters in the food chain and adversely affect human health [8]. Fly ash causes various disorders in human beings such as asthma, bronchitis, silicosis, allergy, fibrosis, cancer, etc. [9]. Dyes are extensively used in textile, paper, leather tanning, printing, plastic, cosm
