“…However, the present experimental values of Q e are 50% higher than those reported in the study of Bishnoi et al 7 and comparable to those of Al-Rub et al 5 It is clear from Table 2 that the phosphorylated algae have higher values of Q m than the unphosphorylated samples. For example, at 50…”

“…These models are the Langmuir and Freundlich isotherm equations. 1,5 The Langmuir model assumes the presence of homogeneously distributed active sites on the adsorbent surface. The finite active site pattern leads to the formation of a monolayer of the adsorbate molecules on the adsorbent surface.…”

“…The remarkable increase of industrial processes and human activities intensified environmental contamination and pollution problems 1−3 The accumulation of heavy metals in the environment leads to many health problems on one hand 4,5 and to the deterioration of many ecosystems on the other hand 6 As a consequence, there are ever increasing legislative standards in most countries that impose treatment processes to reduce heavy metal concentrations or to recover them where feasible. The metals ions of primary concern according to the World Health Organization are those of aluminum, cadmium, chromium, cobalt, copper, iron, manganese, mercury, lead, arsenic, and nickel.…”

A series of batch lab-scale experiments were performed to investigate the performance of dead phosphorylated algal biomass of Spirogyra species for the bioadsorption of Cu +2 ions from aqueous solutions. FT-IR and SEM analyses were performed to characterize the phosphorylated and raw algae. The SEM analysis indicated that the phosphorus content increases by about 5 times. The isotherm equilibrium data indicated that phosphorylation enhances the removal of Cu +2 from water by about 20%. The experimental isotherms fit well to Langmuir models with R 2 values close to 0.99.Adsorption kinetic study was conducted to investigate the effect of initial Cu +2 concentrations, pH, and adsorbent dose on the loading capacity of algal biomass. The optimum pH for the process was around 6 and the corresponding maximum loading capacity was 65 mg/g. The pseudo second-order kinetics successfully modeled the kinetic results with R 2 values closed to 0.99. The thermodynamic results indicated that the bioadsorption process is endothermic and spontaneous at initial Cu +2 concentrations lower than 100 mg/L. The results were promising and encourage the design of a continuous process using algal biomass to remediate water polluted with heavy metals.

“…The adsorption mechanism involving three sorbates is much more complex than in dual systems, due to chemical interactions among metal ions and with biomass, and also depends on ionic radii and electronegativities [34]. Nevertheless, an additional test was carried out at C 0 = 1.0 mM of each metal with both biosorbents.…”

The red microalgae Porphyridium cruentum (S.F. Gray) Nägeli usually was used as feeds, a pigment for food and cosmetic, and antiviral activity that might be became industrial interest. Similar to another microalgae, P. cruentum has an ability to remediate heavy metals pollution, however research on it still limited. This research was conducted in order to find out the accumulation of Pb, Cd, Cr, and Cu on the P. cruentum. A laboratory experiment were developed with different concentrations. Based on this research, P. cruentum with the treatment of 1 mg/L had reduced higher Cu, Pb, Cd, and Cr concentrations rather than 3 and 5 mg/L concentrations, respectively. This was also similar to the BCF, that in day 8 in order of Cu > Cr > Cd > Pb, respectively; however, in day 15 was Cu > Pb > Cd > Cr. The length of treatment influenced BCF value. P. cruentum was good for bioremediation of heavy metal pollution, with the advantage of the short of accumulation time.
