Question 1: You have carried out an investigation into the pigments that make up chlorophyll. Use the chromatogram you obtained when carrying out this investigation. Clearly explain the separation technique of paper chromatography in terms of partition. Calculate the Rf value of one of the constituent pigments and compare it to the book value. A paper chromatography was used to separate the pigments that make up chlorophyll to analyse‚ identify‚ and quantify the components‚ using paper (stationary

Abstract The article describes a technique for processing liquid radioactive waste water using membrane techniques to single out only radioactive waste components without affecting the salt ballast. This solution dramatically reduces the amount of radioactive concentrates to be long-term storage‚ and provides an opportunity to re-use treated water and chemicals. Keywords. Liquid radioactive waste‚ radioactive waste water purification‚ reverse osmosis‚ selective extraction of radionuclides. Introduction

SynopsisThe objective is to determine the amount of Sulphate in anhydrous Barium Sulphate precipitate by gravimetric method. Gravimetric method is by the quantitative determination of the mass of anhydrous Barium Sulphate precipitate. Barium sulphate precipitate is form when Barium Chloride is added excessively to a hot given Sulphate solution slightly acidified with concentrated Hydrochloride acid. The white precipitate of hydrate Barium Sulphate formed is than digest‚ filtered out‚ washed and dried

A-CN-K (Al2O3- (CaO*+Na2O)-K2O) diagram A–CN–K ternary plot is useful tool to evaluate weathering trends in the source rock and to estimate K-metasomatism [Nesbitt and Young (1982‚ 1984); Fedo et al.‚ 1995]. The ideal weathering lines are parallel to A-CN boundary because the removal rates of Na and Ca from plagioclase are greater than the removal rate of K from k-feldspars. On the A–CN–K ternary plot (Fig.6.16) the samples are plotted more or less close to A - K boundary indicating that removal

The Effectiveness of a Paper Charcoal as an Alternative Fuel Source Objectives: This study aims to compare the effectiveness of a paper charcoal and a wood charcoal in producing fire. It specifically aims to determine: 1. Which can last longer between the paper charcoal and wood charcoal as fuel source. 2. Which is more effective to use as a fuel source. Hypothesis: There is no significant difference between the paper charcoal and the wood charcoal
