Background & objective: Synthetic dyes are extensively used in various industries such as textile, leather tanning, plastic, pulp and paper. Since dyes are toxic and even carcinogenic, discharging dye-containing wastewater into the environment poses serious environmental and health problems. Therefore, the purpose of this paper was to evaluate the removal of Reactive Red 120 from aqueous soluti...

Background and Purpose: This study aimed to investigate the adsorption of Acid Blue 62 (AB62) as an anionic dye from aqueous solution onto as SBA-15/Polyaniline (SBA-15/PAni) mesoporous nanocomposite a low-cost adsorbent and feasible. Materials and Methods: Fourier transform infra-red spectroscopy (FTIR), Filed Emission Scanning Electron Microscope (FESEM), Transmission Electron Microscope (TE...

in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...

Background and purpose: The aim of this study was to investigate the efficiency of Fe3O4 nanoparticles synthesized by the chemical co-precipitation method for removal of black acid 1 from aquatic solutions. Materials and methods: In an experimental study, the Fe3O4 nanoparticle was synthesized by the chemical co-precipitation method using Fe+2 and Fe+3 solution in the presence of N2. The eff...

In attempts to remove toxic metal lead, distinct types of algae biomass have been scrutinized as alternatives to conventional physicochemical technologies. In this research, the absorption of  Lead by nanoalgae Scenedesmus sp. was studied at concentration of10 to 100 mg/L, pH 3 to 8, temperature 15 to 40 °C and exposure time of 10 to 60 minutes)in a batch culture system. The concentration of Le...
