Preliminary study on brominated dioxins/furans and hydroxylated/methoxylated PBDEs in Baltic cod (Gadus morhua) liver. Comparison to the levels of analogue chlorinated co-occurring pollutants.
Mar. Pollut. Bull. 96 , 165-75, (2015) Low pg levels of PBDD/Fs in 0.8-38.9 pg g(-1) (fat) range (mean 14.2 pg g(-1)) observed in the tested cod liver samples were significantly lower than levels of their chlorinated analogues (25.1-95.9 range, 37.7 mean pg g(-1) fat). Brominated furans dominated ... |

Fluoride adsorption properties of three modified forms of activated alumina in drinking water.
J. Water Health 12(4) , 715-21, (2014) The study describes the removal of fluoride from drinking water using activated alumina (AA). AA was modified with H2SO4, FeCl3 and a combination of the two to enhance fluoride adsorption. The AA adsorbents were characterized using Brunauer-Emmett-Teller surf... |

Nanocomposites with functionalised polysaccharide nanocrystals through aqueous free radical polymerisation promoted by ozonolysis.
Carbohydr. Polym. 135 , 256-66, (2015) Cellulose nanocrystals (CNC) and starch nanocrystals (SNC) were grafted by ozone-initiated free-radical polymerisation of styrene in a heterogeneous medium. Surface functionalisation was confirmed by infrared spectroscopy, contact angle measurements, and ther... |

A dendrimer-like hyper branched chitosan beads toward fluoride adsorption from water.
Int. J. Biol. Macromol. 78 , 280-6, (2015) The present study reports a novel approach for the preparation of polyamidoamine grafted chitosan beads (PAAGCB) via Michael addition followed by protonation of PAAGCB to get protonated PAAGCB (H(+)-PAAGCB). Various metal ions viz., Al(3+), Ce(3+), La(3+) and... |

Assessment of two extraction methods to determine pesticides in soils, sediments and sludges. Application to the Túria River Basin.
J. Chromatogr. A. 1378 , 19-31, (2015) Pressurized liquid extraction (PLE) and Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) extraction methods were optimized for the simultaneous determination of 50 pesticides in sediment, soils and sewage sludge. For QuEChERS development, several buf... |
