摘要: In this paper, the NiS nanoparticles are prepared and characterized by x-ray powder diffraction scanning electron microscopy. The showed excellent adsorption properties toward sunset yellow (UA) dye. effect of solution pH, adsorbent dosage (0.005–0.020 g), contact time (0.5–30 minutes), initial UA concentration (5–40 mg L−1) on extent was investigated modeled artificial neural network. experimental equilibrium data analyzed Langmuir, Freundlich, Tempkin, D–R isothermal models. It seen that well presented Langmuir model with a maximum capacity 333.3 mg g−1 at 26°C. Kinetic studies various dosages concentrations show high removal percentage (>90%) achieved within 15 minutes. follows pseudo-second-order rate model. were applied to train multilayer feed-forward network three inputs one output Lev...
