In this study, a polymer pH-indicator was synthesized by sulfonation of poly(styrene-co-acrylic acid) with concentrated sulfuric acid. The synthesized polymer pH ...
Abstract: Based on the analysis of the deficiencies of HAZOP, it is presented that the integration of HAZOP with LOPA can obtain the HAZOP-LOPA evaluation method, which can further reduce the risk ...
High molecular weight polyaromatic hydrocarbons (HMW-PAHs) are environmentally ubiquitous and recalcitrant chemicals containing four or more fused benzene rings in their chemical structures and cause ...
