Modification of cyanobacterial bloom-derived biomass using potassium permanganate enhanced the removal of microcystins and adsorption capacity toward cadmium (II)

Functionalized metal–organic framework as a new platform for efficient and selective removal of cadmium(ii) from aqueous solution

“…In order to understand the cadmium adsorption kinetics in Cu3(BTC)2-SO3H, the experimental data collected at the initial cadmium concentration of 1 mg/L in pH 6.0 were fitted with the Lagergren pseudo-first-order kinetic model and pseudo-second-order kinetic model. The pseudo-first-order and pseudo-second-order kinetic models can be described as: 41,42 ln (qe-qt) = ln (qe) -k1t (4) t q t = 2 2 1 e q k + e q t (5) where qe (mg/g) and qt (mg/g) are the amounts of the metal ions adsorbed at equilibrium and at time t (min), respectively; k1 (1/min) and k2 ((g/mg)/min) are the kinetic rate constants for the pseudo-first-order and the second-order models, respectively. The validities of these two kinetic models are examined and depicted in Fig.…”

“…2,3 In particular, cadmium is known to directly damage the nervous, reproductive, renal, and skeletal systems, and can also cause some cancers. 4,5 Therefore, the efficient removal of cadmium from wastewater disposed from industrial and mining processes is of urgent need.…”

Effect of cations in the background electrolyte on the adsorption kinetics of copper and cadmium and the isoelectric point of imogolite

“…Among the TE pollutants, Cd and Cu are the most common and are frequently studied because of their toxicity and abundance in the effluents [1][2][3][4][5][6][7][8][9][10]. The WHO has stipulated that the maximum concentrations of Cd and Cu in water for human consumption should not exceed 0.01 and 1.5 mg·L -1 , respectively [11].…”

Ameliorative effect of propolis and nanopropolis supplementation against oxidative stress induced by Microcystis aeruginosa in Oreochromis niloticus

“…The global expansion of cyanobacterial harmful algal blooms (CyanoHABs) is a serious threat to the ecological integrity, ecosystem services, safe use, and sustainability of inland and coastal waters (Paerl and Otten, 2013) which has become more frequent in many countries of the world and they are predicted to be a rapidly expanding global problem (Shao et al, 2014). In recent years, microalgal blooms and their ecotoxicological potential have drawn substantial attention, particularly because of the threat they pose to human health and the environment (Corbel et al, 2015).…”
