background: lead (pb) is a heavy metal that is widely utilized in industries. it contaminates soil and groundwater. its non-biodegradability, severe toxicity, carcinogenicity, ability to accumulate in nature and contaminate groundwater and surface water make this toxic heavy metal extremely dangerous to living beings and the environment. therefore, technical and economic methods of removing pb ...

The present study seeks to investigate the capacity of polyaniline/titanium dioxide (PAn/TiO2) and Polypyrrole/titanium dioxide (PPy/TiO2) nano-adsorbents to adsorb Congo red anionic dye (CR) from aqueous solution. The variables effective in CR adsorption, including adsorbent dose, pH of the solution, contact time, initial dye concentration, and temperature were examined. The study yielded the ...

Abstract Natural mulberry leaves and carboxylic acid-modified (Morus alba L.) were used for the first time to scrutinize effects of modification on retention efficiency an anionic dye (Remazol Brilliant Blue R (RBBR)) from aqueous solutions suggest economical promising adsorbent treatment dye-contaminated water. The characterization adsorbents was accomplished through common techniques includin...

industrial wastewater included the dyes one of the important sources of environmental pollution that founded in loom wastewater which are harmful for human health and environment. therefore, the purpose of this research was investigated removal of rb5 dye from aqueous solution by using of adsorption onto activated red mud as an cheap adsorbent. this research was experimental- laboratorial study...

A novel inorganic–organic biosorbent, polyethyleneimine (PEI)-modified nanocellulose cross-linked with magnetic bentonite, was prepared for the removal of Cu(?) from water. Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) showed that amino carboxyl groups were successfully grafted onto structure. The adsorption performance various factors, using investigated. results ...

The efficiency of activated parthenium hysterophorous as an adsorbent for removing Pesticide mixture from water has been studied. Batch mode adsorption experiments have been conducted by varying pH, concentration, adsorbent dose and contact time. Pesticide removal was pH-dependent and found to be maximum at pH 2.0. The maximum removal of pesticides was achieved within 100 min after the start of...
