Removal of copper(II) from aqueous solution by Jordanian pottery materials

Theoretical models of sorption kinetics including a surface reaction mechanism: A review

“…that the estimation of the sorption rate cannot be done when only the equilibrium data are at disposal (This observation is supported by the data presented in [78,122,130], for instance). A potential limitation is the significantly smaller number of papers reporting good applicability of the pseudo-first order equation.…”

Combined cation-exchange and extraction chromatographic method of pre-concentration and concomitant separation of Cu(II) with high molecular mass liquid cation exchanger after its online detection

“…However, preconcentration and separation of an analyte is usually necessary before its monitoring. In this regard, the most widely used techniques are solvent extraction [3], coprecipitation [4][5][6], ion chromatography [7], adsorption [8,9], cloud point extraction [10], electrochemical deposition [11] and solid phase extraction (SPE) [12][13][14]. But, except SPE all other techniques are extremely expensive, when the metals are in large volumes of relatively low concentrations [15].…”

Porainu kvartāra mālu keramikas granulu sorbcijas īpašības

“…Šo trūkumu palīdz novērst apdedzinātas mālu keramikas izmantošana ūdens attīrīšanas tehnoloģijās. Literatūrā atrodams ļoti daudz materiālu par keramikas materiālu izmantošanu smago metālu jonu saistīšanai no ūdens šķīdumiem [5][6][7][8][9][10][11]. Klasiskajā keramikas tehnoloģijā ir labi zināms, ka, apdedzinot keramikas materiālus, to porainība un materiāla īpatnējā virsma samazinās.…”
