“…Other biosorbents reported have exhibited Q max values at 37.3 mg·g −1 with grape stalks, 15.5 mg·g −1 with cork powder and 98 mg·g −1 with raw clinoptilolite, showing that Staphylococcus xylosus biomass can be included among the most efficient Fe(III) biosorbents and used further as a potential biosorbent system for arsenic removal [27,28].…”

“…It has high potential for separation, purification, adsorption and ion exchange depending on the type of exchangeable cations and their specific positions within the framework structure [4][5][6][7][8][9][10][11][12]. Additionally, high selective cation exchange capacity makes clinoptilolite rich mineral useful in waste water treatment especially in the removal of ammonium and heavy metals such as copper, cadmium, iron, lead, nickel, silver and zinc [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. For the removal of anionic heavy metals such as Cr(VI) and As(V), clinoptilolite rich mineral is not as efficient as it would be in cationic heavy metals and ammonium removal.…”

“…Water for the preparation of solutions was tap water purified by a five-stage reverse osmosis system (Aqualive, s.r.o., Košice, Slovakia). The equilibrium experiments were carried out with a series of PET flasks containing 0.1 dm 3 (V) of metal ion solution of different initial concentrations (C 0 = 1 to 4000 mg.dm −3 ) prepared from iron sulphate and a fixed dosage of sorbent (C a = 1 g.dm −3 ) which were agitated for 2 h in a rotary shaker at 3.33 s −1 , with a temperature control at 25 • C, what was sufficient for the metal ions adsorption to reach an equilibrium, based on previous studies [6,8,[10][11][12][13]15,16]. The initial pH of the solution was not adjusted.…”

“…Zeolites are often used in water treatment for drinking water purposes. Both zeolites and bentonites are also used in wastewater treatment [ 8 , 9 , 10 ]. A study [ 8 ] of Fe(III) removal by zeolite in its raw form and treated with Na 2 S 2 O 8 and HNO 3 at 20 °C and 70 °C reported a maximum sorption capacity of about 100 mg.g −1 except for treatment with HNO3 at 70 °C with a maximum sorption capacity of only 45 mg.g -1 .…”
