Removal of ammonium ions from aqueous solutions using alkali-activated analcime as sorbent

Autor: Hanna Runtti, Elavarasi Sundhararasu, Janne Pesonen, Sari Tuomikoski, Tao Hu, Ulla Lassi, Teija Kangas

Publikováno v: ChemEngineering; Volume 7; Issue 1; Pages: 5

Five alkali-activated analcime (ANA) sorbents (ANA-MK 1, ANA 2, ANA 3, ANA-MK 4, and ANA-MK 5) were developed for ammonium (NH4+) ion removal. Acid treatment and calcination were used as pre-treatments for analcime, and metakaolin (MK) was used as a

Vanadium removal and recovery from liquid waste streams

Autor: Zhang, R. (Ruichi)

Vanadium is an important and strategic metal that has been widely used in many technological fields. Its consumption has significantly increased during recent decades. Therefore, primary resources are considered insufficient to satisfy demand and man

A common agricultural soil test can identify legacy P hotspots in a drainage ditch network

Autor: Golnaz Ezzati, Tuomas Mattila

Highlights •Agricultural ditches accumulate legacy P and present a risk for water quality. •Mehlich-3 soil test can identify P saturation and total legacy P amount. •Use of a common soil test allows broad scale mapping of high P risk hotspots.

Bisphenol A removal from water by biomass-based carbon : Isotherms, kinetics and thermodynamics studies

Autor: Juhola, Riikka, Runtti, Hanna, Kangas, Teija, Hu, Tao, Romar, Henrik, Tuomikoski, Sari

Biomass-based carbon was modified and used as an efficient bisphenol A (BPA) sorbent. The simple and environmentally friendly modification method produced sorbent with a capacity of 41.5 mg/g. The raw material was modified with FeCl3 (Fe-CR), treated

Experimental and computational studies on sulphate removal from mine water by improved lime precipitation

Autor: Nurmesniemi, E.-T. (Emma-Tuulia)

Lime precipitation has been used for the treatment of mine water for decades; however, the impact of precipitation conditions is not adequately known. In this thesis, four aspects related to the removal of sulphate from mine water by lime precipitati

Utilisation of industrial by-products in water treatment:carbon-and silicate-based materials as adsorbents for metals and sulphate removal

Autor: Runtti, H. (Hanna)

Pollutant (such as metals and sulphate) contamination exists in the wastewaters of many industries, including mining operations, metal plating facilities, and tanneries. Adsorption is one of the most commonly used processes for the removal of polluta
