Ammonia removal from leachate solution using natural Chinese clinoptilolite

Adsorption of Nutrients from Stormwater Using Sawdust

“…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].…”

Ammonium removal from solution using ion exchange on to MesoLite, an equilibrium study

“…This can be compounded by the ever decreasing nitrogen discharge consent levels [3,12,13] imposed by regulatory bodies on wastewater treatment companies. In addition to this, rapid economic development and the improvement of the standard of living in developing nations will result in the production of much more treated wastewater [14].…”

Çam Kozalak Tozunun Bi̇osorbent Olarak Kullanilrak Sudan Amonyumun Uzaklaştirilmasi

“…This relatively high adsorption capacity shows the strong electrostatic force of attraction between the ammonium molecules and the biosorbent bending-sites [30]. Furthermore, in order to situate the raw pinecone powder among the raw mineral adsorbents used to remove ammonium ions from aqueous solutions, a comparison based on Langmuir saturation capacity, Qm, has been made and indicated that the sawdust (0.165 mg/g) was not more efficient than soils (0.28, 0.9 mg/g) [31]; sawdust (1.7 mg/g) [5]; sepiolite (1.47 mg/g) [32] and some zeolites (0.9 mg/g) [21] (1.27 mg/g) [33], and could be considered as a promising material to remove ammonium even when compared with some efficient zeolites as Natural Chinese clinoptilolite (2.02 mg/g) [33], Chabazite (2.94 mg/g) [34]. It should be noted that our study used raw have a lower surface area.…”
