1 The research was set to study the low-temperature production of HF via reaction of synthetic CaF2 and waste H2SO4. sulfuric acid CCR4-NOT transcription complex subunit 8 Homo sapiens
2 The reaction of commercial CaF2 and 70% H2SO4 had a higher absorbed-HF yield of 61.7% than synthetic CaF2 and 70% waste H2SO4, which had a yield of 36%. sulfuric acid CCR4-NOT transcription complex subunit 8 Homo sapiens
3 This was due to the higher purity of the commercial CaF2 and fewer interference ions in H2SO4. sulfuric acid CCR4-NOT transcription complex subunit 8 Homo sapiens
