Abstract:
Wastewater produced from industrial sector including cosmetic industry introduced hazardous organic compounds such as phthalates which are categorized as endocrine-disrupting chemicals (EDC) into the environment, posing significant serious risk to ecosystem and agricultural productivity. These substances are resistant to traditional treatment methods and persistent in environment. In this study, an electrochemical treatment method with three electrode system i.e., reference, counter and working electrode was developed in order to breakdown of phthalates from industrial wastewater, with emphasis on assessing the treatment efficiency and then reuse of the treated water for agricultural purposes. For this Carbon nanotubes (CNTs) were synthesized by Chemical vapor deposition (CVD) method using lemon peel as a carbon source. Modification of carbon nanotubes were accomplished by using sodium molybdate (Na2MoO4) and nickel-aluminum (Ni-Al). These materials were used as electrode for the wastewater treatment in the electrochemical cell. The performance of the synthesized materials toward the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) was evaluated using linear sweep voltammetry (LSV), cyclic voltammetry (CV) to evaluate their activity toward the hydrogen evolution reaction (HER) and oxygen evolution reaction(OER). The experiments were conducted in both acidic (H2SO4) and alkaline (KOH) media with different scan rates and different phthalate concentrations of30 ppm, 60 ppm, and 90 ppm, and chrono potentiometry was used to assess the phthalates degradation in real cosmetic industrial wastewater. The removal efficiency showed by modified CNTs for removal of phthalates was 93% and88% respectively. The treated wastewater was further applied to pot experiment to examine the effect of plant growth with 2 varieties of wheat i.e. Akbar-19 and Desi variety was examined. Growth parameters like Root length, shoot length, root and shoot weight and rot and shoot dry weight was monitored. Both varieties of wheat showed improved growth irrigated with treated WW as compared to those irrigated with untreated WW. This research shows that synthesis of modified CNTs was proven to be an efficient catalyst in electrochemical cell in terms of phthalate removal and treated WW showed significant growth in wheat.
