Abstract

Agricultural wastes are residues from the growing and first of raw agricultural products such as fruit, vegetables, meat, poultry, dairy product and crops. 100 g each of bean’s shields, groundnuts shields and melons shields were randomly collected from five different locations and labeled A, B, C into polythene bags and taken to the laboratory for analyses. The composite of each five collected samples were formed and analyzed. Moisture content of A: 20.03 ± 0.057 %, B: 10.06 ± 0.111 % and C: 17.16 ± 0.058 %; % ash content of A: 12.03 ± 0.021 %, B: 13.06 ± 0.045 %and C: 20.03 ± 0.057 %; % water soluble ash for A: 25.10 ± 0.100, B: 18.01 ± 0.012 and C: 30.00 ± 0.000 while % alkalinity of A: 34.03 ± 0.021, B: 30.00 ± 0.000 and C: 35.16 ± 0.045. Working standard solutions of potassium, K were prepared and emission intensity in triplicates of each was measured: average emission intensity for 10, 20, 30, 40 and 50 ppm are 52.86 ± 0.07, 105.76 ± 0.05, 158.73 ± 0.06, 211.56 ± 0.05, 264.46 ± 0.05 respectively and a standard curve for K was plotted. Average emission intensity of K in samples A, B and C solutions were measured as 106.26 ± 0.058, 123.03 ± 0.057 and 134.36 ± 0.058 respectively. These were read up in the K standard curve and extrapolated to determine concentration (ppm) of K in A, B and C: 19.9, 24.5 and 25.7 respectively. On the other hand, working standard solutions of potassium, Na was prepared and emission intensity in triplicates of each was measured: average emission intensity for 10, 20, 30, 40 and 50 ppm are 24.06 ± 0.058, 48.16 ± 0.058, 72.26 ± 0.058, 96.36 ± 0.058, 120.46 ± 0.058 respectively and a standard curve for Na was plotted. Average emission intensity of Na in samples A, B and C solutions were measured as 38.58 ± 0.052, 30.17 ± 0.051 and 42.36 ± 0.058 respectively. These were read up in the Na standard curve and extrapolated to determine concentration (ppm) of K in A, B and C: 15.4, 13.5 and 20.0 respectively. The results buttress high emission intensity hence, high concentration (ppm) of K and Na in melon shields followed by groundnut shields and beans shields.
