Red mud has been used to develop effective adsorbents to remove phosphate from aqueous solution. The effects of different dosage, pH of solution and reaction time on adsorption have been examined in batch experiments. It was found that red mud samples show higher removal efficiency for phosphate. The results showed that phosphate removal efficiency was found to be 97 % with optimal reaction conditions initial phosphate concentration 100mg L−1, red mud dosage 10g L−1, pH 2.0, respectively. The phosphate removal efficiency of the red mud adsorbents decreases with increase of pH.

Amine-SiO2 material was synthesized and applied as a novel adsorbent for nitrate and phosphate removal from aqueous solution. The characterization of Amine-SiO2 were done by using TGA, FTIR, BET, and SEM analyses. Results showed that Amine-SiO2 had higher nitrate and phosphate adsorption capacity of 1.14 and 4.16 times, respectively, than commercial anion exchange resin (Akualite A420). In addition, Amine-SiO2 also had good durability with stable performance after at least 10 regeneration times, indicating that this material is very promising for commercialization in the future as an adsorbent for water treatment.

Optical absorption spectroscopy provides evidence for individually dispersed carbon nanotubes. A common method to disperse SWCNTs into aqueous solution is to sonicate the mixture in the presence of a double-stranded DNA (dsDNA). In this paper, optical characterization of dsDNA-wrapped HiPco carbon nanotubes (dsDNA-SWCNT) was carried out using near infrared (NIR) spectroscopy and photoluminescence (PL) experiments. The findings suggest that SWCNT dispersion is very good in the environment of DNA existing. Additionally, its dispersion depends on dsDNA concentration.
