以碱性氧化物为转化剂制备高枸溶性磷实验研究
Experimental Study on Preparation of High Citric Acid Soluble Phosphorus by Alkaline Oxide
摘要
Abstract
To create a phosphate fertilizer that is rich in citrate-soluble content to aid in the growth of macadamia nuts,researchers utilized low-quality phosphate rock and muck acid to produce water-soluble phosphorus products.They then tested the impact of various conversion a-gents such as alkaline magnesium oxide,calcium oxide,yellow phosphorus slag,and calcium magnesium phosphate fertilizer on the citrate-soluble phosphorus levels and conversion rates.Results indicated that using alkaline magnesium oxide as the conversion agent with 12%added showed the best conversion effect,resulting in a citric acid soluble phosphorus content of 21.78%and a conversion rate of 69.18%.Similarly,using alkaline calcium oxide with 16%added as the conversion agent yielded the best results,with a citrate-soluble phosphorus content of 25.80%and a conversion rate of 75.61%.When alkaline yellow phosphorus slag was used as the conversion agent with 20%added,the best con-version effect was observed,resulting in a citric acid soluble phosphorus content of 18.27%and a conversion rate of 53.87%.Finally,using calcium magnesium phosphate fertilizer as the conversion agent with 25%added showed the best results,with a citric acid soluble phosphorus content of 21.73%and a conversion rate of 55.15%.关键词
