This paper has researched on the adsorption of Ni in water using Laminaria japonica and Undaria pinnatifida. The dependence on pH and nickel concentration of the adsorption was studied. Batch experiments results showed that the adsorptive capacity of Laminaria japonica and Undaria pinnatifida was 2.933mg/g and 0.985 mg/g of adsorbent. The Langmuir model was used to describe the adsorption equilibrium...
Like BPA, bisphenol F (BPF) was used in the production of epoxy resins and polycarbonates and it was shown to be a xenoestrogen. The photodegradation of bisphenol F (BPF) in the presence of algae was investigated under the irradiation of metal halide lamps placed in cooling trap for maintaining constant temperature by water circulation (lambdages365 nm, 250 W). The effect of algae concentration, initial...
Manganese copper composited algaecide (MCC) was prepared by permanganate and acid-soluble copper chloride. The effectiveness of MCC on Microcystis aeruginosa removal and the effective period of MCC were studied, pH influence on the water sample was inspected, and the feasibility of MCC as a new algaecide was discussed. The results showed that inactivation effect on Microcystis aeruginosa by MCC was...
The process of biosorption of heavy metal ion Cu(II) by immobilized brown algae Laminaria japonica is discussed in this paper, with the adsorption characteristics of L. japonica investigated as a parameter of initial pH, initial concentration of Cu(II), particle size, algal dose and temperature. The maximum adsorption of Cu(II) ion on L. japonica biomass was observed at pH 3-5. The higher initial...
