“…Powdered activated carbon (PAC) adsorption is a physico-chemical removal process for pharmaceuticals (Lima et al, 2014;Mailler et al, 2015) and other organic pollutants (Quinlivan et al, 2005;Ho et al, 2011;Ghafoori et al, 2014). Studies show that the addition of Fe species can improve the performance of PAC adsorption Park et al, 2015).…”

Pharmaceuticals are detected at trace levels in waters. Their adverse effects on aquatic ecosystems and human health demand novel pharmaceutical removal technologies for treating wastewater effluents. Iron (Fe) or manganese (Mn) may play important roles in these new technologies since these metals are abundantly available at low costs and are known to contribute to organic conversions via physico-chemical, chemical, and biologically related processes. Few reviews describe and discuss Fe-or Mn-based technologies for the purpose to remove pharmaceuticals from water. Therefore, we review the current literature sorted into the three removal mechanisms, that is., through physico-chemical, chemical, and biological processes. The principals, performance, and influential parameters of these three types of technologies are described. Current and potential applications of these technologies are critically evaluated in order to identify advantages and challenges. In addition, the Fe-or Mn-based technologies which are currently not used but promising to further develop to remove pharmaceuticals cost efficiently are proposed.

“…Alguns estudos (CHOI et al, 2006;LIMA et al, 2014a) têm revelado que tais microcontaminantes orgânicos não são removidos em sua totalidade pelos processos convencionais de clarificação e filtração empregados nas estações de tratamento de água, demandando a utilização de técnicas complementares de tratamento para a remoção de tais microcontaminantes (WESTERHOFF et al, 2005). Vários estudos conduzidos por pesquisadores brasileiros mostram que o uso de técnicas avançadas de oxidação MEIRELES;LANGE, 2015;MELO et al, 2009;MANIERO;DEZOTTI, 2008;BILA et al, 2007), de adsorção com carvão ativado em pó ou granular (LIMA et al, 2014b; 2016) ou de separação por membranas (BRANDÃO & AMORIM, 2012; MIERZWA; AQUINO; VERAS, 2009) pode ser promissor na remoção de fármacos e desreguladores endócrinos de águas contaminadas.…”

RESUMO Fármacos e desreguladores endócrinos são encontrados em águas naturais brasileiras, incluindo alguns mananciais de abastecimento, também em função da baixa cobertura de coleta e tratamento de esgotos no Brasil. Nesse cenário, o presente trabalho intentou avaliar a remoção de três fármacos - sulfametoxazol (SMX), diclofenaco (DCF) e 17β-estradiol (E2) - em água destilada por meio da oxidação com cloro (hipoclorito de sódio), variando-se a dose de cloro e o tempo de contato em ensaios de batelada. As soluções cloradas foram analisadas, ainda, por cromatografia acoplada à espectrometria de massas para identificação de eventuais subprodutos de oxidação. Para tempo de contato de 10 min e dose de cloro de 1,5 mg.L-1, foi observada remoção média de 61% para DCF, 36% para E2 e 33% para SMX. Apenas para o DCF verificou-se diferença estatisticamente significativa (α=0,05) para dose de cloro de 3,0 mg.L-1. A oxidação seguiu modelo cinético de pseudossegunda ordem, com valores de k2 de 0,0168 L.µg.min-1 para SMX (para ambas doses testadas), de 0,0133 e 0,0798 L.µg.min-1 para DCF, e de 0,0326 e 0,0289 L.µg.min-1 para E2, para doses de cloro de 1,5 e 3,0 mg.L-1, respectivamente. Por fim, verificou-se que o aumento do tempo de contato favoreceu a oxidação dos fármacos, ainda que com a perspectiva de formação de subprodutos para SMX e E2.

“…[13,14] Recognizing the limitations of the conventional water treatment processusually consisting of coagulation, flocculation, sedimentation or flotation, filtration and disinfection unitsfor removal of organic contaminants has fostered the development of technologies specific for that purpose. [15] Membrane filtration, advanced oxidative processes and adsorption on activated carbon are worthy of mention. The construction and maintenance cost of the two first technologies tends to be favourable to the use of the adsorption, mainly in bigger treatment plants in which water sources are more compromised.…”

The aim of this study was to evaluate the performance of two forms of basic granular activated carbon (GAC), mineral (pH = 10.5) and vegetal (pH = 9), for the removal of three pharmaceuticals, as sulphamethoxazole (SMX), diclofenac (DCF) and 17β-estradiol (E2), from two different matrices: fortified distilled (2.4-3.0 mg L(-1) and pH from 5.5 to 6.5) and natural (∼1.0 mg L(-1) and pH from 7.1 to 7.2) water in a bench scale. The Rapid Small-Scale Column Test used to assess the ability of mineral and vegetal GAC on removal of such pharmaceuticals led to removal capacities varying from 14.9 to 23.5 mg g(-1) for E2, from 23.7 to 24.2 mg g(-1) for DCF and from 20.5 to 20.6 mg g(-1) for SMX. Removal efficiencies of 71%, 88% and 74% for DCF, SMX and E2, respectively, were obtained at breakthrough point when using mineral GAC, whereas for the vegetal GAC the figures were 76%, 77% and 65%, respectively. The carbon usage rate at the breakthrough point varied from 11.9 to 14.5 L g(-1) for mineral GAC and from 8.8 to 14.8 L g(-1) for vegetal GAC. Mineral CAG also exhibited the best performance when treating fortified natural water, since nearly complete removal was observed for all contaminants in the column operated for 22 h at a carbon usage rate of 2.9 L g(-1).
