Nowadays, the nature of active species and role peroxydisulfate (PDS) was still unclear in advance oxidation systems based on activation PDS by CuO with non-radical pathway. In this paper, a sheet like containing two kinds Cu2+ prepared, one which electron deficient (Cu2+-h). The CuO/PDS system showed extraordinarily utilization (172.3%) for BPA degradation (after four cycles PDS). main mechani...

In this paper, we demonstrate for the first time that poly(m-phenylenediamine) (PMPD) nanospheres and nanorods can be selectively synthesized via chemical oxidation polymerization of m-phenylenediamine (MPD) monomers using ammonium persulfate (APS) as an oxidant at room temperature. It suggests that the pH value plays a critical role in controlling the the morphology of the nanostructures and f...

Occupational allergic contact eczema and asthma caused by bleaching agents is seen in hairdressers. Bleaching agents contain persulfate salts, which are known to induce immediate reactions such as rhinitis, asthma, contact urticaria, and anaphylaxis. The immunologic mechanism is not, however, fully understood. The specific inhalation challenge test is considered to be the gold standard for diag...
