“…While not a direct chemical modification, microwave heating can result in physical and chemical alterations to AC, when compared to the conventional activation process. This can include variations in the internal surface area, altered pore size distributions and changes to the native surface chemistry [72,73]. Microwave treatment as a means to prepare AC may prove to be beneficial in terms of lower power consumption and preparation time.…”

Abstract:To ensure the availability of clean water for humans into the future, efficient and cost-effective water purification technology will be required. The rapidly decreasing quality of water and the growing global demand for this scarce resource has driven the pursuit of high-performance purification materials, particularly for application as point-of-use devices. This review will introduce the main types of natural and artificial contaminants that are present in water and the challenges associated with their effective removal. The efficiency and performance of recently developed materials for water purification, with a focus on activated carbon, carbon nanotubes and graphene will be discussed. The recent advances in water purification using these materials is reviewed and their applicability as point-of-use water purification systems discussed.

“…In studies of the area, the activated carbon adsorbent has been one of the most widely used in color removal and treatment of textile effluents. Furthermore, the development of low-cost alternative adsorbents has been the focus of many researches (Choi et al, 2015;Fernandez et al, 2015;Gonzalez et al, 2009;Kazmierczak-Razna et al, 2015;Khandelwal and Gaikwad, 2011;Saucier et al, 2015;Zhao et al, 2015).…”

In this study, the potential of bone char for Royal Blue Tiafix and Black Tiassolan dyes adsorption from aqueous solutions was evaluated. The adsorbent was characterized physically and chemically by adsorption/desorption of N 2 at 77 K, scanning electron microscopy, X-ray diffraction, and infrared spectroscopy. The equilibrium adsorption results for bone char can be successfully modeled by the Langmuir and Freundlich isotherms. Pseudo-first-order and pseudo-second-order models were used to describe the kinetic data and rate constants were evaluated. Kinetics of each dye was found to follow pseudo-second-order rate kinetic model, with great correlation (higher than 0.99). In order to reduce the number of experiments to achieve better dye removal efficiency, a 2 3 full factorial design with three central points and six axial points was applied in the equilibrium experiments. The variables analyzed were agitation, temperature, and pH.

“…The most known applications are water treatment (remedying bodies of water, effluent treatment and sanitary landfill and water filters lixiviate); air purification (toxic gases and combustion gases removal); food and drink industrialization (sweetener purification, edible oils, glycerin, wine, organic and inorganic acids); pharmaceutical production (color and compounds removal from some drugs); medicinal use (toxic products elimination; tablets, curatives, odor control filters and masks productions), use in automotive vehicles (adsorbing combustible emissions or inside odors from them). It also is useful on oil refineries as a support for catalysts, gas storage, dehumidification (mold elimination and food conservation); in mining; and in the electronic industry (AVELAR et al, 2010;SALES et al, 2012;BAUTISTA-TOLEDO et al, 2014;SAUCIER et al, 2015;TMR, 2016).…”

“…Depollution projects of those water sources depend on much elaborated politics that revolves around population awareness and water treatment. New technologies that use AC are indispensable for removing pollutants that are causing increasing severe environmental damage (CARVAJAL-BERNAL et al, 2015;SAUCIER et al, 2015;HÚMPOLA et al, 2016;WERNERT;DENOYEL, 2016).…”

Considering the water scarcity problems facing many countries, the need for water reuse can make activated carbon (AC) an essential product for modern society. In this context, to contribute with better activated carbons that could be used to serve in water treatment, this article discusses these materials production, using bamboo as raw material, and analyses their application effectiveness. The bamboo was collected, transformed into activated carbon, by simultaneous chemical and physical activations, and named H 3 PO 4 / H 2 OAC. The obtained material was characterized by its yield, apparent density, ash content, thermogravimetric analysis, surface area, methylene blue and iodine indexes, pH and point of zero charge analysis, scanning electron microscopy and Boehm titration method. The AC was used as adsorbent for removing the metribuzin, 2,4-dichlorophenoxyacetic acid and furadan pesticides. The H 3 PO 4 /H 2 OAC had a surface area of 1196.30 m² . g -1 and the obtained adsorption capacity was elevated for furadan (868.98 mg . g -1 ), metribuzin (756.47 mg . g -1 ) and 2,4-dichlorophenoxyacetic acid (274.70 mg . g -1 ). DESENVOLVIMENTO DE CARVÃO ATIVADO A PARTIR DE BAMBU (Bambusa vulgaris) PARA REMOÇÃO DE PESTICIDAS DE SOLUÇÕES AQUOSASRESUMO: Considerando os problemas de escassez de água enfrentados por vários países, a necessidade de reuso das águas, pode fazer do carvão ativado (CA) um produto imprescindível à sociedade moderna. Neste contexto, para contribuir com a melhoria de carvões ativados que poderão servir ao tratamento de água, este artigo, discute a produção desses materiais, que teve o bambu, como matéria prima, e analisa a eficácia de sua aplicação. O bambu foi coletado, transformado em carvão ativado mediante ativação química e física simultânea e denominado CA H 3 PO 4 /H 2 O. O material obtido foi caracterizado pelo rendimento, densidade aparente, teor de cinzas, análise termogravimétrica, área superficial, índices de azul de metileno e de iodo, análise do pH e ponto de carga zero, microscopia eletrônica de varredura e método titulométrico de Boehm. O CA foi usado como adsorvente para a remoção dos pesticidas metribuzin, 2,4-diclorofenoxiacético e furadan. O CA H 3 PO 4 /H 2 O apresentou área superficial de 1196,30 m² . g -1 e a capacidade de adsorção obtida foi elevada para o furadan (868,98 mg . g -1 ), metribuzin (756,47 mg . g -1 ) e 2,4-diclorofenoxiacético (274,70 mg . g -1 ).
