“…Hackbarth et al (2014) and Girardi et al (2014) reported a total of acidic binding sites of 2.5 mEq/g (Carboxylic: 1.5 mEq/g; Sulfonic: 1.0 mEq/g). Beyond that, using a mass action law to describe the ion-exchange equilibrium data, the following selectivity constants were obtained: , , , , for carboxylic groups and , , , , for sulfonic groups.…”

“…Among heavy metals in wastewaters, cadmium, lead, copper and zinc are considered having a high priority due to their toxicity and high disposal rate, thus, removal of these metals of industrial effluents is mandatory (Kosasih et al, 2010;Hackbarth et al, 2014). A large number of industries including, petroleum refining, battery manufacturing, plating, mining, electroplating, metal processing, textile, tanneries, paint manufacture, pesticides, pigment manufacture, are sources of heavy metal contamination (Vilar et al, 2008).…”

“…A lei de ação das massas, considerando os grupos funcionais carboxílicos monovalentes e os grupos sulfônicos inicialmente saturados com íons de sódio, e as reações de troca com Cu 2+ , Zn 2+ e H + , foi utilizada para ajustar os dados experimentais para ambos os sistemas ternários, Na + /H + /Cu 2+ ou de Na + /H + /Zn 2+ . Uma descrição detalhada da equação da lei de ação das massas pode ser encontrada em Hackbarth et al (2014 Figura 2 -Dados experimentais do equilíbrio de biossorção e modelo de troca iônica para diferentes valores de pH utilizando a alga-Na: cobre (a) e zinco (b).…”

“…Entre os diferentes tipos de algas, as algas marrons tem provado ser um ótimo biossorvente para remoção de metais pesados, apresentando muitas vezes capacidades de adsorção semelhantes às resinas de troca iônica. Sendo assim, as algas marinhas podem competir em termos de preço e eficiência com as resinas de troca iônica disponíveis no mercado Hackbarth et al, 2014).…”

“…Alginates and fucoidans contained in the cells walls of P. canaliculata are poly-anions due to the presence of carboxylic and sulfonic groups, and as a consequence this alga can act as a natural cation exchanger. This ability is widely documented in the scientific literature, and it was proposed to use P. canaliculata biomass to sequestrate and remove metal ions (zinc, iron, copper, trivalent chromium, lead, nickel) from industrial wastewaters [64][65][66].…”
