in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
Background and Objective: Reactive dyes are the newest dyes in textile industry. They may cause environmental problems. The aim of this study was to remove Reactive Black 5 (RB5) in aqueous solutions with activated carbon that was made from grape wood. Materials and Methods: The activated carbon was synthesized by potassium carbonate with impragnation ratios of 1:0.25 at different temperatures...
Abstract Background and aims: Clean air is one of the basic needs for human health and well-being. However, along with economic growth and development, transportation, urbanization and energy consumption have also risen and provide many concerns such as air pollution, which require urgent and wide attention. Air pollution in the worldwide is considered as a risk factor for human health and one...
This work investigates three types of biochar (bamboo charcoal, wood pellet, and coconut shell) for postcombustion carbon capture. Each is structurally modified through physical (H2O, CO2) chemical (ZnCl2, KOH, H3PO4) activation to improve capture performance. Three methods (CO2 adsorption isotherms, CO2 fixed-bed adsorption, thermogravimetric analysis) are used determine the capacity. The resu...
Many vital ecosystem processes take place in the soils and are greatly affected by the increasing active nitrogen (N) deposition observed globally. Nitrogen deposition generally affects ecosystem processes through the changes in soil biochemical properties such as soil nutrient availability, microbial properties and enzyme activities. In order to evaluate the soil biochemical responses to eleva...
Considerable amounts of heavy metals have been discharged to the environment since the beginning of the industrialization. Consequently, the concentration of toxic metals in rivers, lakes and oceans has increased notably. Cadmium, arsenic, copper, zinc, lead and other metals have been listed by the USEPA as the most common contaminants in wastewaters. Cadmium, in particular, has been identified...
A bamboo cannon is a homemade reusable firecracker with kerosene oil used as the fuel. A 13-yearold boy suffered burn on face, upper and lower limbs with a TBSA of 25% caused by the blast of a bamboo cannon. Ten percent of the area of both lower limbs required grafting, and the rest healed spontaneously. The burn is in fact a flame burn with kerosene oil from the blasted bamboo acting as the ac...
Introduction: There are different methods for removal of cadmium from aqueous solutions. Adsorption based methods are among the bests. One of the most important aspects for adsorption techniques is the availability of an accessible and economical adsorbent. This study aims to investigate cadmium removal from aqueous solutions by walnuts shell waste. Materials and Methods: Walnut Shell (WS) was...
