Activated charcoal derived from Moringa oleifera, Manihot esculanta, Carica papaya are efficient for waste water treatment and dye removal. Adsorption techniques are used to remove the non-bio degradable pollutants. The produced carbon was exemplified using Scanning Electron Microscopy and Fourier Infrared spectroscopy. The discoloration rate was higher at an optimum pH of 5 for all three samples and at an adsorbent dosage of 0.02g/100ml of effluent and the equilibrium was obtained in 10 minutes. Thus, the adsorbents have the prospective for realistic applications. Adsorption isotherms was evaluated by the Freundlich, Langmuir isotherms and higher linear attenuation coefficients showed that the experimental data shows a better fit to Freundlich model (R2 = 0.9987) for Manihot esculenta, Langmuir model for Carica papaya and Moringa oleifera (R2 = 0.9931) (R2 = 0.9959). Kinetic studies were also executed for all the adsorbents and for Manihot esculenta data en suite well to pseudo-second order model (R2 = 0.9966), for Carica papaya (R2 = 0.9986) and for Moringa oleifera investigational data en suite well with Pseudo-first order (R2 = 0.9916) respectively.

Iron molybdate was prepared via simple solution chemistry method and the photocatalytic degradation of a pesticide (endosulfan) was investigated under visible light irradiation. As-prepared (Fe 2 (MoO 4 ) 3 ) was characterized using scanning electron microscope (SEM), x-ray diffraction (XRD), energy dispersive x-ray spectra (EDX), diffused reflectance spectroscopy (DRS) and Zeta particle sizer techniques. The iron molybdate crystallite size was 36 nm, while grain size was in the range of 160-340 nm. The particles of polymetallic compound were spherical, highly porous and with fluffy texture indicating high surface area. DRS revealed Fe 2 (MoO 4 ) 3 was active under visible region since band gap value calculated was 2.7 eV. Response surface methodology (RSM) was employed for the optimization of photocatalytic activity (PCA) of Fe 2 (MoO 4 ) 3 as a function of catalyst dose, H 2 O 2 dose, solution pH and concentration of endosulfan and up to 77% degradation was achieved at optimum conditions, which was monitored by UV/vis spectroscopy. In response to endosulfan degradation, the chemical oxygen demand (COD) and total organic carbon (TOC) were reduced up to 76% and 67%, respectively. Results revealed that iron molybdate is highly efficient photocatalyst for the degradation of endosulfan under solar light irradiation and could possibly be used for the treatment of endosulfan containing wastewater.

Adsorption is an efficient, cost-effective, and eco-friendly method for the treatment of phosphorus from wastewater. This work presents the adsorptive removal of phosphate ions in aqueous solution using coal slag (CS) from a thermal power plan. The surface morphological analysis showed that the CS particles were around 50 µm with a surface area of 9.20 m 2 g −1 and adsorption average pore width of 6.42 nm, offering the high capability for phosphate ions adsorption. The optimising phosphate ions adsorption conditions were investigated based on various parameters, including contact time, pH, and amount of absorbent. The experimental results showed that the maximum loading adsorption capacity was 21.63 mg g −1 in the concentration range of 0-30 mg L −1 under optimising conditions (i.e. pH of 6, adsorbent dosage (0.1 g vol −1 used) and contact time of 45 min). Furthermore, the use of CS offers several benefits like reducing the sample pre-treatment steps for costly, less time-consuming and reliable methods.
