H acid and DSD acid are two important substrate of dyes, which wastewater is treated more difficulty because of containing multi-component, with high chroma value and nonbiodegradability. A treatment way of this wastewater by extraction based on chemical association was

4,4'-Diamino-2,2'-stilbene disulfonic acid (DAS), a key intermediate in the synthesis of dyes and fluorescent whitening agents, has been purported to have weak estrogenic properties based on apparent structural similarity with diethylstibestrol (DES) and unsubstantiated reports of male reproductive dysfunction in

Organic ultraviolet (UV) rays absorbents have been used as sunscreen materials, but they may pose a safety problem when used at high concentration. In order to prevent direct contact of organic UV rays absorbent to the human skin, a typical

Two advanced oxidation processes, Fenton's reagent oxidation and ozonation, were used for pretreatment of a 4,4'-diaminostilbene-2,2'-disulfonic acid (DSD-acid) manufacturing wastewater on a laboratory scale. The results showed that both methods are suitable for partial removal of chemical oxygen demand (COD)

We showed previously that the disulfonic stilbene DNDS (4,4'-dinitrostilben-2,2'-disulfonic acid) was a potent blocker of outwardly rectifying chloride channels (ORCC). The studies reported here were designed to quantify the relationship between electron withdrawal by the 4,4'-substituents and blocker potency. Specifically
