Gold precipitate from aqua regia solution using hydroquinone. It was so simple and attaining 99.99% purity after firing was an incredible delight. Refining the silver chloride left over from the solution was a little more of a chore but I got to within 80%.
Product Short Description: Specially designed to used in any pressure washing machine range or mopping. Its High penetration formula deep into recesses and crevice of equipment and machinery to chase out soils without disassembling. The resultant run-off will not harm tarmac or a
Product Technical Specification:
Remarks:
Advanced chemical formulation with a wetting agent and penetrating action formulation...
Uses and Benefit A surfactant (Surface-Active Agent).
Advantages:
1. Very effective as a bactericide.
2. It will form gels, emulsify oil and lower the surface tension of water. A lower surface tension allows the soap to come in contact with the greater surface area than with water alone.
Why it is better than ordinary Liquid Soap?
Disadvantages of ordinary soap:::
1. When used in hard water, soap can produce a scum - calcium and magnesium salts present in hard water react with the soap to cause this to happen. Soapless or synthetic detergents do not leave a residual film behind.
2. Considerable rinsing is required to remove soap scum.
3. Soap may produce a greasy build-up on the surface which can be slippery.
4. More expensive than synthetic detergents.
Product Short Description: TPTZ method is most common method for low range Iron determination from the sample.
Product Technical Specification:
Remarks:
2,4,6- Tris-(2’ - Pyridyl )-s-Triazine ( TPTZ ) or also can be use like 2,4,6-Tripyridyl-s-triazine. Solution of (TPTZ), .001 M were prepared by dissolving 0.312 gram of compound in a view drops of hydrochloric acid and diluting to 1 ltr with water.
2,4,6-Tripyridyl-s-triazine solution of (TPTZ) is useful for the calorimetric determination of iron. The Intense violet colour formed by TPTZ with iron(II) is due to the ion {Fe(TPTZ)2}+2, with only two of the three pyridyl group of each TPTZ ligand attached to the Iron atom.
This reagent is also used for determination of iron in silicates, burnt refractories, and limestone etc
