Zeoliti su alumosilikatni minerali, koji zbog izomorfne zamjene silicija aluminijem imaju svojstva kationskih izmjenjivača, te mogu vezati razne metalne ione iz voda. Vrlo rasprostranjen prirodni zeolit je klinoptilolit, Na3K3 Al6Si30O72 2

Zeoliti su alumosilikatni minerali, koji zbog izomorfne zamjene silicija aluminijem imaju svojstva kationskih izmjenjivača, te tako mogu vezati metalne ione iz voda. Nakon tretmana otpadnih voda zeolitima, pročišćena voda može se ponovno koristi

A number of alternative methods have been reported in the literature, all of which use an analytical separator column without suppressor. These methods differ from each other chiefly in the mode of detection employed. Inorganic anions may be separate

One of the most significant commercial application of natural zeolites is the removal of metal ions from wastewater. Some metalcomplex dyes used for dyeing wool are copper complexes. Copper toxicity and its harmful impact on the environment are well

Bakar je sastavni dio nekih metalokompleksnih bojila. Poznato je njegovo toksikološko i štetno ekološko djelovanje pa je neophodna kontrola njegova sadržaja u bojilu i na tekstilnom materijalu obojadisanom tim bojilima kao i u otpadnim vodama. Is

Metals are integral part of some metal complex dyes. The harmful action of heavy metals is known and it is necessary to supervise the contents of heavy metals in dyestuffs, in a dyed textile material and in textile waste waters. It is estimated that

Teški metali su redovito pratioci bojadisanja, bilo kao sastavni dijelovi bojila ili sudjeluju u samom procesu bojadisanja. Zbog svoje štetnosti na zdravlje čovjeka i okoliš, proces bojadisanja potrebno je provoditi tako da se uz minimalne koncen

Istaknuta su toksikološka svojstva i štetno djelovanje teških metala u procesima oplemenjivanja tekstila. Tragove bakra i željeza nastoji se ukloniti iz sustava za peroksidno bijeljenje kako ne bi došlo do katalitičkog raspada peroksida i time
