The catalytic activity of water-washed manganese nodule leached residue (WMNLR) samples improved by treating with acetic acid. The effects of acetic acid treatment on the physicochemical properties and catalytic activity ...

The present study reports removal of As(V) by adsorption onto laboratory-prepared pure and Cu(II)-, Ni(II)-, and Co(II)-doped goethite samples. The X-ray diffraction patterns showed only goethite as the crystalline phase. ...

Treatment of wastewater containing lead and iron was examined using two different ion-exchange resins namely Duolite ES 467 (containing amino-phosphonic functional groups) and a chelating ion-exchange resin (containing ...

A new aurone, 4,6-dihydroxy-2-[alpha,alpha-(4-hydroxyphenyl)hydroxy]methylene-3(2H)-benzofuranone (2) and two rare metabolites viz. selin-4(15)-en-1beta,11-diol (5) and 5,7-dihydroxy-3-O-beta-D-glucopyranosyl-1''' --> 6" ...

Most agricultural soils contain large reserves of phosphorus ( P), a considerable part of which accumulates as a consequence of regular applications of P fertilizers. However, a greater part of soil phosphorus, approximately ...
