Leached barium sulfate
WebA method based on Ge(Li) γ-ray spectrométry is applied to the determination of 224 Ra (t 1 2 = 3.64 days) in natural waters. The 224 Ra is first removed from several hundred liters of water by preconcentration onto manganese dioxide-impregnated acrylic fibers. The fibers are leached, radium is coprecipitated with barium sulfate, and the γ-ray activity is … Web씨스켐닷컴 - 화학시장정보, 석유화학제품가격, 화학뉴스, 화학플랜트신증설프로젝트, 화학제조업체, 화학컨설팅시장조사, 석유화학계통도, 화학제품사전, CAS No., 스페셜티케미칼, 파인케미칼, 정밀화학, 화학시장보고서, 화학단행본, 난연제(Flame Retardant), 플라스틱첨가제, 가소제(Plasticizer), 도료 ...
