In this research, the removal of Reactive Red 198 dye (RR-198) by Cuttlefish bone powder was investigated. The adsorbent was prepared in laboratory conditions and ground by ASTM standard sieves (60-100 mesh). The progress of the process is monitored spectrophotometrically by measuring the absorbance of dye at 518 nm wavelength. In addition, the effects of process parameter...

According to the increasing development of the mankind, social and technology activities in the earth, various industry is in a state of uncontrolled growth. In the present study, magnetite/nickel oxide mixed metal oxide nanoparticles (FNMMO NPs) were prepared by a simple method assisted by ultrasonic waves and applied as a novel adsorbent to dispose of dye wastewater. The morphology and chemic...

introduction: discharge of textile wastewater causes the reduction of sunlight penetration, interferes with the receiving waters ecology and damage the environment. the aim of this study was to determine the removal efficiency of reactive blue 19 dye from aqueous solutions by cuttlefish bone powder. materials & methods: this study was performed experimentally and in laboratory scale. in this re...

industrial effluents, especially the textile industry are discussed as one of the fundamental problems of the environment .dyes are materials with complex structures that enter into the wastewater from different stages of the textile industry. colors are often toxic, carcinogenic and mutagenic. this study investigated the absorption efficiency of reactive red 198 dye from aqueous solutions by p...

Synthetic dyes are among the most common contaminants of the environment. Therefore, the aim of this study was investigation the removal of Basic Blue 41 (BB41) and Methylene Blue (MB) from industrial effluents by useing raw and modified rice stems. In this study raw and modified rice stems treated chemically with Citric Acid (CA) and were used to explore the potentiality of rice stems for ...

Background: The rapid increase in agricultural and industrial development has made heavy metal pollution a serious environmental problem and public health threat; therefore, removal of heavy metals from water is important. The current study prepared DNPH@SDS@Fe3O4 nanoparticles as a novel and effective adsorbent for removal of Hg(II) ions from an aqueous solution. Methods: A selective adsorben...

background and aims: from the past studies, it has been proved that consumption of heavy metals by humans may cause several chronicle problems like cancer, kidney and liver damage, high blood pressure and low blood pressure problems and etc. so, it has become very crucial to remove these heavy metals from industrial wastewater. the aim of this study was to find out a low cost and easy available...
