The present study investigated a novel method of alkaline ferricyanide leaching to extract palladium (Pd) from Western Australian disseminated platinum-group metal (PGM) oxide ore that bears Ni and Cu. While cyanide has been used leach Pd, it is well known for its toxicity large consumption in the presence base metals. A more benign alternative, form ferricyanide, evaluated this research serve ...

Background and objectives: Safflower (Carthamus tinctorious L.) florets contain valuable red and yellow pigments and are used in food, textile dying, and pharmaceutical industries. Red carthamine pigment is formed from a yellow precursor, precarthamine, through an oxidation reaction at the end of flowers' maturation stage. The present study was conducted to find out the most effective ...

In this work, spherical Pt nanometer-scale particles supported on the poly (m-toluidine)/Triton X-100 film modified carbon nanotube paste electrode (Pt/PMT (TX-100)/MCNTPE) was used as a potent catalyst for electrooxidation of formaldehyde (HCHO) in both 0.5 M H2SO4 and 0.1 M NaOH solutions. The obtained results showed that utilization of TX-100 as an additive during the electropolymerization p...

In 1935, Shay and Gershon-Cohen showed that luminal perfusion of the duodenum of human subjects with sodium bicarbonate solution produced a rapid emptying of a barium sulphate meal from the stomach. More recently it was shown by Brown et al. (1966) that, in the dog, the instillation of alkaline solutions into the duodenum also increased motor activity in denervated, transplanted gastric pouches...
