- Executive summary:
A study was performed to determine the particle size distribution of test chemical within range of 150 µ to 10 µ. The study was conducted in accordance with OECD guideline 110 and according to Adapted from IS: 2720 (Part 4)1985 (Reaffirmed 2006); Indian Standard METHODS OF TEST FOR SOILS, PART 4 GRAIN SIZE ANALYSES. The particle size distribution was determined to be in the range of 150 micron to 53 micron
Reference
OBSERVATION
The particle size distribution of test chemical is determined by observing or keeping a record of original weight of test chemical taken, weights of empty petri dishes, weight of test chemical and Petri dishes and total amount of test chemical retained in each sieve after tapping. Total amount of test chemical lost after sieving is determined by subtracting original test chemical taken. Percentage of the test chemical retained in each sieve is calculated and recorded. Type of distribution: Mass based distribution
CALCULATIONS
The particle size distribution of the test chemical is calculated using the formula:
Total amount of test item after sieving = ( original test item taken - Total test item retained after sieving)
% of test item = Test item retained after sieving *100
Total test item retained after sieving
Amount of test item weighed (g)=10.005 Method run time(minute)=10 min |
