Chitosan interact with polyphosphate ions to form nanoparticles with different diameters depending on the mutual ratio among them. Three nanoparticles have been prepared and were characterized by spectral and X-ray diffraction tools. TEM analysis revealed there diameters. The nanoparticles were thoroughly studied for wastewater treatment such as the removal of Total Suspended Solid (TSS), Bioch...

This paper describes the preparation of new adsorbents derived from sugarcane bagasse and wood sawdust Manilkara sp. to remove zinc II ions from electroplating wastewater. The first part deals with the chemical modification of sugarcane bagasse and wood sawdust, using succinic anhydride to introduce carboxylic acid functions into the material. The obtained materials modified sugarcane bagasse M...

This report presents the results of PRCs waste audit study for the metal finishing industry. The study was conducted to identify opportunities for waste reduction available to the metal finishing industry and to develop a generic audit protocol that can be used by metal finishers to assess their own waste reduction opportunities. The study emphasized technologies available to smalland medium-si...

Metal ceramic partial fixed dental prostheses have been commonly used for the replacement of missing teeth for many years. Because of an increase in the price of gold, base metal alloys have been the choice of alloy for the fabrication of metal ceramic restorations in many dental clinics. Some major disadvantages of base metals are their corrosion and the dark coloration they may cause at the c...

Water is one of the most stable and abundant complexes on nature that can be polluted with natural and human factors. Therefore, it is necessary to ensure a timely warning for possible accumulation of polluting metal in natural waters in order to protect public health. One of the economic and rapid methods for elements removal is displacement of metals by biosorption. The purpose of this study ...

Hospital laboratory wastewater has been considered to significantly change the degree of contamination of especially the hospital wastewater. The present study investigated the hospital clinical laboratory wastewater and the pollution loads were assessed for pathogens, heavy metals, and organic materials. Composite samples were collected from clinical laboratory wastewater of a 350-bed hospital...

The first of these chemicals, mineral spirits, is known by a number of different names. Benzine, petroleum spirits, mineral turpentine, naphtha and painters naphtha are just a few of the synonyms of mineral spirits. This solvent is actually a mixture of a number of different hydrocarbons. It is distilled from petroleum and is composed of chemicals having generally five to seven carbons. It repr...

Many communities and villages around the world face serious problems with lack of sanitation especially in disposing of the wastewater-black water and grey water from the houses, or wash outs from animal rearing sheds. Across the world diverting wastewater to the surroundings or to the public spaces are not uncommon. This is responsible for contaminating drinking water sources causing health ri...

During the past several years, waste produced by the electroplating industry has attracted attention due to the level of pollutants found in the waste stream, the difficulty associated with treatment, and the cost of waste disposal. EPA has enacted regulations to control the discharge from plating facilities and estimates that 140 million lb of metal pollutants will be prevented from being disc...
