PRODUCTION OF CARBON PAPER USING CHARCOAL AND BLACK MIX OF USED BATTERY AS PIGMENT D EPARTMENT O F S CIENCE IN COOPERATION WITH THE AND T ECHNOLOGY ABSTRACT The objective of the first part of the study was to find the best ratio of ink using carbon from used batteries and charcoal as pigments. The ink was evaluated on the basis of how much pigment is suspended in the mixture and their shelf life. The second part was aimed at the production of carbon paper. The best kinds of ink were tested

Light Absorption by Photosynthetic Pigments in Silver Beet Abstract The aim of the experiment was to determine the absorption of differing wavelengths of light by individual pigments in the vegetable silver beet. Pigments were extracted from silver beet leaves and separated into chlorophyll a‚ chlorophyll b‚ and carotene via chromatographs. Chlorophylls were then separated and an absorption spectra created using results obtained from a spectrophotometer. It was clear there were two distinct peaks

respiratory pigments; these pigments are metal containing proteins which combine reversibly with oxygen. Respiratory pigments are found within cells of blood and their primary function is to aid in the transportation of molecular oxygen. There are four unanimously recognised respiratory pigments‚ these are; hemoglobin‚ followed by hemocyanin‚ then chlorocruorin and Hemerythrin. These four pigments occur in greater percentages and are far more efficient in carrying oxygen than the few other pigments known

EXPERIMENT 4 ANALYSIS OF HYDROCARBON IN COMMON FUELS BY SOLID-PHASE MICROEXTRACTION (SPME) AND GAS CHROMATOGRAPHY-MASS SPECTROMETRY (GC-MS) Abstract In the analysis the solid-phase microextraction (SPME) and capillary gas chromatography/mass spectrometry (GC/MS) was developed for the identification of volatile compounds (hydrocarbon) in fuel. The samples was used is (kerosene‚ diesel‚ thinner and petrol) and one unknown. After the analyte was extracted by SPME in 20min‚ it directly injected
