Efficient and synergistic removal of tetracycline and Cu(II) using novel magnetic multi-amine resins.

A series of magnetic multi-amine resins (MMARs, named E1D9-E9D1) was proposed for the removal of tetracycline (TC) and Cu(II) in sole and binary solutions. Results showed that the N content of the resins increased sharply from 1.7% to 15.

Insight into the adsorption of PPCPs by porous adsorbents: Effect of the properties of adsorbents and adsorbates.

Adsorption is an efficient method for removal of pharmaceuticals and personal care products (PPCPs). Magnetic resins are efficient adsorbents for water treatment and exhibit potential for PPCP removal. In this study, the magnetic hypercrosslinked resin Q100 was used for adsorption of PPCPs.

[Physiological responses of Ceratophyllum demersum under different nutritional conditions].

With static experiments, this paper investigated the protein and chlorophyll contents, and the peroxidase (POD) and superoxide dismutase (SOD) activities of Ceratophyllum demersum cultured in meso-, eutro- and hypertrophic and Hoagland's solutions. The results showed that the changes of total N (TN) and total P (TP) concentrations in nutrient solutions had an obvious effect on the biosynthesis of C. demersum.
