“…Using renewable resources for contaminant removal through adsorption is becoming more cost-effective method. Some materials have been tested for this purpose, such as sepiolite [11], bittern [12], clinoptilolite [13][14] hardwood mulch [15], and sawdust [16][17][18].…”

“…It is obvious that the urea absorbency of the SN6 and SN8 biochars increased rapidly in the first 3 hours, and then decreased until reached an equilibrium state in 24 hours. It is not consistent with the normal laws [25]. And SN4 had no adsorption effect.…”

“…Radi smanjenja rizika po životnu sredinu i ljudsko zdravlje neophodno je uklanjanje štetnih anjonskih vrsta (nitrati, sulfati, fosfati, arsenati, hromati), kao i teških metala iz otpadnih voda. Za ukanjanje nitrata iz vode je razvijen i opisan širi spektar metoda, od kojih se najčešće primenjuju: jonska izmena [6,7], reverzna osmoza [8], adsorpcija [9], elektrodijaliza i denitrifikacija [10,11]. Međutim, ove trenutno dostupne metode za uklanjanje nitrata, pored svojih individualnih prednosti, imaju izvesna tehnološko-ekonomska ograničenja.…”

“…Lagergren-ov model pseudo-prvog reda, nakon integraljenja i linearizacije, izražava se sledećom jednačinom [33]: (6) gde je: q e -količina sorbovanih nitrata u stanju ravnoteže (mg g ). Grafički prikaz slaganja eksperimentalno dobijenih podataka sa modelom pseudo-prvog reda, za ispitivani opseg početnih koncentracija nitrata (2 -100 mg dm -3 ), predstavljen je na slici 6.…”
