Dinitrobutylphenol Removal from aqueous Environments by Synthesized magnetic particles from walnut hard-shell ash

<p>Dinitrobutylphenol is a toxic and resistant pollutant that pollutes the environment by producing toxins chemical wastewater. Present paper aims to study efficiency of magnetic particles walnut hard shell ash as cheap bi-compatible adsorbent for removable DNBP from aqueous environments. This was conducted at laboratory scale studied most important parameters including contact time, pH, dose, concentration temperature on process. Walnut magnetized its properties were using SEM, FTIR, XRD, BET techniques. The fitness data Langmuir Freundlich isotherms. Results showed pH=7, 25°C , 700 mg adsorbent, within 50 min, removal with initial 20 reached 93%. isotherm studies this process coefficient 99% conforms equation it has higher conformity maximum adsorption 142.88 mg/g. Magnetic ashes natural bio-friendly able efficiently remove persistent material environments industrial wastewaters.</p>
