Cellulose wastes of a wood and paper factory were used to produce activated carbon. Several chemical agents under various conditions were used for production of activated carbon and hence their adsorption properties have been evaluated. In addition the effect of process parameters such as raw material, chemical agent concentration, impregnation ratio, carbonization temperature, carbonization ti...

In recent years, several researchers have shown the good performance of alkali activated slag cement and concretes. Besides their good mechanical properties and durability, this type of cement is a good alternative to Portland cements if sustainability is considered. Moreover, multifunctional cement composites have been developed in the last decades for their functional applications (self-sensi...

Background & Aims of the Study: High concentration of nitrogen compounds in water and wastewater can be caused various problems and diseases such as methhemoglobinemia and eutrophication. The aim of this study was investigated nitrification and denitrification from wastewater using integrated fixed film activated sludge (IFAS) includes powder activated carbon. Materias and Methods: The labo...

background: the efficacy of nh4cl-induced activated carbon (nac) was examined in order to adsorb rr198, an azo reactive model dye, from an aqueous solution. methods: the effects of ph (3 to 10), adsorbent dose (0.1 to 1.2 g/l), dye concentration and contact time on the adsorption efficiency were investigated. results: the results showed that the removal of dye was highest at a solution ph of 7 ...

this study examined the adsorption behavior of two cationic dyes used in textile industries (cibasic red 46 and ci basic blue 3) on tunisian clay used in pottery. the ability of pottery clay to remove thebasic dyes from aqueous solution was compared to that of the commercial powdered activated carbon (pac)and raw clay. physicochemical characteristics of these adsorbents were performed by boehm ...
