Effective removal of ruthenium (III) ions from wastewater by amidoxime modified zeolite X

Herein, we proposed an affordable and facile way of treating the hardening of water from local groundwater and seawater sources. This was facilitated by synthesizing zeolitic materials via an effortless and affordable method from readily available disposed of waste materials. Firstly, by converting waste aluminium (scrap wire cables, takeaway foil, cans, and spray aerosol bottles) along with disposed of silica gel into active zeolitic materials with the aid of a conventional domestic microwave. Small amounts of the produced zeolites (NaX and NaA) were utilized in the removal of the hardness of water (10 g.L-1), showing elimination of Ca 2+ and Mg 2+ ions within 30 minutes, removing 90% of the total hardness (> 1000 ppm). The spent zeolite samples can be further used for more than two consequent cycles, then the regeneration can be promoted by using NaCl solution at ambient conditions. The total price for the synthesis of 1 kg of the zeolite produced herein is 14 $/kg. This is 70% lower than the price of commercial zeolites available in the market. Our proposed facile route in zeolite preparation could potentially change the traditional costly softening treatment techniques. It also minimizes the use of extra chemical materials, templates and multistep procedures. The excellent hardness removal capacity in groundwater and seawater using synthesized zeolite samples could open doors for various applications.

“…Zeolites as crystalline aluminosilicates have a microporous structure with elevated thermal stability and high chemical resistance. Due to their thermal stability, high exchange capacity, easy modification and selectivity, zeolites are considered to be excellent adsorbents, which have large adsorption capacity with good cationic exchange properties [1].…”

Zeolity należą do rodziny uwodnionych minerałów glinowokrzemianowych, zawierających metale alkaliczne oraz alkaliczno-ziemne.Są zauważane ze względu na ich zdolność wymiany jonowej oraz odwrotnej dehydratacji. Ich struktura zawiera wewnętrznie połączonewgłębienia zajęte przez duże kationy metali oraz cząsteczki wody. Bentonity to iły tworzone często poprzez alterację popiołu wulkanicznego, zawierające głównie minerały smektytu a zazwyczaj montmorillonitu. Wykazują silne właściwości koloidalne a ich objętośćwzrasta kilkukrotnie podczas wejścia w kontakt z wodą, tworząc w ten sposób galaretowatą i lepką ciecz. Specjalne właściwości bentonitu(hydratacja, puchnięcie, absorpcja wody, lepkość, tiksotropia) powodują, że jest to cenny materiał dla szerokiej gamy zastosowań. Celemtego artykułu jest udokumentowanie zdolności zeolitów oraz bentonitów do usuwania jonów żelaza oraz różnych innych zanieczyszczeńz wody. Analiza powierzchni zeolitu i bentonitu została wykonana za pomocą bardzo czułego urządzenia analitycznego – XPS (roentgenowska spektroskopia fotoelektronowa)
