WebAug 30, 2024 · The main objective of this study consists in the synthesis of a layered double hydroxide (LDH) clay doped with magnesium and aluminum in order to test the removal of phosphates and ibuprofen in water. Two different LDH composites are assessed: oven-dried (LDHD) and calcined (LDHC). Single adsorptions of phosphate and ibuprofen showed up … WebAs one of the most abundant herbivorous zooplankton groups in tropical waters, small-bodied cladocerans may influence the lower trophic levels (microbial loop, phytoplankton), thereby affecting size structure ( Pagano, 2008 ), biomass, and community composition of phytoplankton, as also confirmed in mesocosm experiments ( Silveira et al., 2010 ).
