ผลของรังสีแกมมาและรังสีแกมมาร่วมกับโซเดียมไฮดรอกไซด์ แคลเซียมไฮดรอกไซด์และยูเรีย ต่อการย่อยสลายโมเลกุลของวัสดุเหลือทิ้งทางการเกษตรบางชนิด / วาสินี เที่ยงสุข = Effects of gamma ray and gamma ray with sodium hydroxide, calcium hydroxide and urea on the molecular degradation of some agricultural wastes / Wasinee Thiungsook
Molecular degradation of peanut shell, corncob and cassava shell by gamma ray and gamma ray with sodium hydroxide, calcium hydroxide and urea at various dose of gamma ray irradiation, various concentrations of chemicals and degrading times were studies. Degradation with sodium hydroxide, calcium hydroxide and urea were also studied. The results indicated that combination treatment by gamma ray at 50-100 kGy with 20% Ca(OH)[subscript 2] in 7-21 days gave the optimum decreasing value of cellulose and hemicellulose (90% decreasing) in both corncob and cassava shell, while in peanut shell the optimum decreasing value was gamma ray irradiation at 75-100 kGy with 20% NaOH in 2-3 days (85% decreasing). Molecular degradation of cassava shell by 30% Ca(OH)[subscript 2] in 7 days and 21 days for peanut shell and corncob showed 80% decreasing value of cellulose and hemicellulose
