Effect of solution pH on the dynamic of biosorption of Cr(VI) by living plants of Salvinia minima
(Elsevier Science, 2015-01)
Salvinia minima is a widely distributed floating fern that bioaccumulates high concentrations of heavy metals and is a promising species for Cr(VI) removal from polluted waters. Metal bioaccumulation efficiency of aquatic ...
Efeito do cloreto de sódio na dieta, dureza e ph da água na sobrevivência, crescimento e fluxos iônicos de juvenis de jundiá (Rhamdia quelen)
(Universidade Federal de Santa MariaBRZootecniaUFSMPrograma de Pós-Graduação em Zootecnia, 2008-04-22)
The purpose of this study was to verify the effect of dietary salt (NaCl) supplementation, water hardness and pH on growth, survival and ionoregulation of silver catfish (Rhamdia quelen) juveniles. In the first experiment, ...
Biomineralization changes with food supply confer juvenile scallops (Argopecten purpuratus) resistance to ocean acidification
Future ocean acidification (OA) will affect physiological traits of marine species, with calcifying species being particularly vulnerable. As OA entails high energy demands, particularly during the rapid juvenile growth ...
Photo-Fenton degradation kinetics of low ciprofloxacin concentration using different iron sources and pH
(2013-05-01)
The aim of the present study was to compare the degradation kinetics of low (1 mg L-1) and high (25 mg L-1) concentrations of ciprofloxacin (CIP) aiming to decrease the concentration of additives and evaluate the pH ...
