Boron doped diamond films have been deposited by large area hot-filament CVD (HFCVD) on silicon, silicon carbide, and different industrial electrode materials, like niobium, tantalum, titanium, tungsten, zirconium, and graphite on areas up to 40 cm * 60 cm ...
The electrochem. oxidn. of phenol in the presence of NaCl for wastewater treatment was studied at Ti/SnO2 and Ti/IrO2 anodes. The presence of NaCl catalyzes the anodic oxidn. of phenol only at Ti/IrO2 anodes due to the participation of electrogenerated ClO ...
A process for prepg. a water sol. polymer comprises: providing a polymn. reaction mixt. comprising one or more polymerizable ethylenically unsatd. monomers; polymg. the ethylenically unsatd. monomers; and adding to the reaction mixt. during polymn. one or ...

The controlled biodegradation of ametryn and methomyl has been performed, in accordance with the OECD Zahn-Wellens/EMPA procedure, by use of an enriched mixture of activated sludge collected from three domestic waste-water-treatment plants (WWTP). During t ...
Thin boron-doped diamond films were prepd. by HF CVD (hot filament chem. vapor deposition technique) on conductive p-Si substrate (Si/diamond). The morphol. of these Si/diamond electrodes was investigated by SEM and Raman spectroscopy. The electrochem. beh ...
After treatment with an appropriate base (butyllithium or sodium amide), 2-alkenyltris(2-methoxymethoxyphenyl)phosphonium salts carrying an allyl, crotyl, or prenyl (3-methyl-2-butenyl) side chain condense with satd. or unsatd. aldehydes to give conjugated ...
A review with 15 refs. with application examples, including mechanism of electrochem. oxidn. of org. compds. in aq. soln., anodic oxidn. of phenol over PbO2, characteristic parameters of electrochem. treatment, and economic considerations. [on SciFinder (R ...
A high mol. wt. water sol. acrylamide based polymer having improved flocculating and dewatering properties is provided. The polymer is prepd. by a process in which a small quantity of a chain branching agent is added to the polymn. reaction mixt. continuou ...

5-amino-6-methyl-2-benzimidazolone (AMBI), used in the manufacture of dyes, was characterised as a biorecalcitrant compound by means of different biodegradability tests. In order to enhance the biodegradability of this important pollutant, the application ...
