TABLE
X : Paper intended to come into contact with dry food. Y : Paper intended to come into contact with wet food and food with fatty surface. Z : Paper for filtration.
APPENDIX-I DETERMINATION OF SOME CONTAMINANTS FROM PAPER INTENDED TO COME INTO CONTACT WITH FOOD LEAD (Pb) The sample from paper will be leached with extraction fluid of pH 2.88 + 0.05 prepared by mixing 5.7 ml of acetic acid in one litre of double distilled water for 18 + 2 hrs. using shaker rotating/moving at 30 + 2 rpm. The metal content of the extract will be determined by separating the extract from the paper matrix by filtration through glass fibre filter with 45 micron pore size. The liquid fraction will be acidified and digested prior to Pb analysis as per Standards. Methods for the Examination of Water and Waste water (APHA, AWWA, WPCF) 18th edition 1992. The metal content of the extract will be determined using Atomic Absorption Spectrometric and Graphite Oven technique. CADMIUM (Cd) The sample from paper will be leached with extraction fluid of pH 2.88 + 0.05 prepared by mixing 5.7 ml of acetic acid in one litre of double distilled water for 18 + 2 hrs. using shaker rotating/moving at 30 + 2 rpm. The metal content of the extract will be determined by separating the extract from the paper matrix by filtration through glass fibre filter with 45 micron pore size. The liquid fraction will be acidified and digested prior to Cd analysis as per Standards. Methods for the Examination of Water and Waste water (APHA, AWWA, WPCF) 18th edition 1992. The metal content of the extract will be determined using Atomic Absorption Spectrometric and Graphite Oven technique. CHROMIUM (Cr+6) The sample from paper will be leached with extraction fluid of pH 2.88 + 0.05 prepared by mixing 5.7 ml of acetic acid in one litre of double distilled water for 18 + 2 hrs. using shaker rotating/moving at 30 + 2 rpm. The metal content of the extract will be determined by separating the extract from the paper matrix by filtration through glass-fibre filter with 45 micron pore size. The Cr+3 and other interfering metals will be precipitated with aluminium sulphate. Cr+6 will be determined from the extract with diphenylcarbazide using spectrophotometry (550 nm). MERCURY (Hg) The sample from paper will be leached with extraction fluid of pH 2.88 + 0.05 prepared by mixing 5.7 ml of acetic acid in one litre of double distilled water for 18 + 2 hrs. using shaker rotating/moving at 30 + 2 rpm. The metal content of the extract will be determined by separating the extract from the paper matrix by filtration through glass-fibre filter with 45 micron pore size. The Hg content of the extract will be determined using cold vapour atomic absorption spectrometric method. Note : For each metal, the metal content of the leaching fluid should be determined simultaneously and subtracted from the metal value of the extract. PENTACHLOROPHENOL (PCP) The sample from paper will be extracted with an organic solvent. The extract is concentrated and acetylated. The determination of PCP is done by gas chromatography. POLYCHLORINATED BIPHENYLS (PCBs) The sample from paper is extracted with boiling ethanolic potassium hydroxide solution. An aliquot of the extract is mixed with water and subjected to extraction with hexane. The PCBs contained in the hexane phase are quantified by capillary gas chromatography using an EC detector. The pattern of the peaks is compared with the pattern of a suitable technical PCB.
