Povidon-iodine ointment

Abstract: The ointment is an oil-in-water emulsion with melting point higher than 50 deg.C, good stability and retentivity. Its components include povidone-iodine 2%, stearic acid 10-15%, super fatty alcohol 6-10%, paraffin oil 0-3.5%, laurinol sodium sulphate 1-2%, potassium iodate 0.3-0.6%, glycerine 0-12%, polyethyleneglycol liquid 30-35% and distilled water 25-35%. During the prepn, various water phase and oil phase components are first mixed at 90 deg.C and povidone-iodine is added slowly after the temp. of mixture decreases to 40 deg.C. The said ointment has ideal disinfectant effect.

Spectrophotometry determination of Congo red in river water samples using nanosilver

Abstract: A spectrophotometric procedure for the anionic diazo dye Congo red was proposed based on nanosilver catalyzed oxidation by potassium iodate in a hydrochloric acid medium. The calibration graph is linear for 0.8–240 mg L−1, and the detection limit is 0.6 mg L−1. Most foreign ions do not interfere with the determination, except for Cu(II), Fe(III), and Cr(VI). The interferences of Cu(II) and Fe(III) could be eliminated by masking with ethylene diamine tetraacetate, and that of Cr(VI) by reducing to Cr(III) with ascorbic acid. The typical features of this procedure are that it is sensitive for Congo red, and the determination could be carried out at room temperature. It had been used for the determination of Congo red in the Ganjnameh river water sample.

Multiple elements chemical etching agent for nickel-titanium alloy film

Abstract: The multi-component chemical etching agent for nickel-titanium alloy film is formed from 1%-25% (V) of fluohydric acid, 0.5%-155 (V) of nitric acid, 2%-20% (V) of hydrochloric acid and etching rate accelerating agent made up by using one kind of potassium iodate, sodium hypochlorite, peroxyacetic acid or hydrogen peroxide or several kinds of their mixtures as main component, and its service performance can be retained by supplementing consumed active components. Said invention possesses high stability for photoresist and several organic compounds, and can ensure the accuracy of graphic transfer, raise the capability for transferring complex mask pattern, and can raise the processed finished product rate and reduce the cost for processing product and treating waste water.
