Micellar-enhanced ultrafiltration (MEUF) was used to remove phenol from simulant aqueous solutions. The effect of groups difference of cationic surfactant on the solubilization of phenol was investigated through orthogonal experiment, namely, surfactants with the same length of hydrocarbon chain but different hydrophilic head group and vice versa. The effects on the solubilization of

Soap skimmings are an intermediate substrate in the production of tall oil from Kraft pulping black liquor. In this study, biodiesel was produced directly from soap skimmings before being processed into tall oil using acetyl chloride and sulfuric acid as accelerators. The effects of the accelerator amount, reaction time, and pH on the production yield were investigated. The yields of biodiesel ...

The deoxyribonucleic acid (DNA) of Escherichia coli B is converted by colicin E2 to products soluble in cold trichloroacetic acid; we show that this DNA degradation (hereafter termed solubilization) is subject to inhibition by infection with bacteriophage T4. At least two modes of inhibition may be differentiated on the basis of their sensitivity to chloramphenicol. The following observations o...

functionalization of multiwalled carbon nanotubes (mwcnts) with nh2 groups under a one pot reaction is studied. during the first step of the reaction, cl and chcl2 groups were attached to the surfaces of mwcnts through an electrophilic addition reaction. in the second step of process, cl atoms were replaced with nh2 and amino groups (ethylene diamine and butyl amine) under a nucleophilic substi...

Immune precipitates were solubilized by the alternative pathway of complement assembled from isolated proteins, i.e., C3, factor B, factor D, properdin, C3b inactivator (C3bINA), and beta 1H. The kinetic curves of solubilization in the isolated system and in EGTA-serum were virtually indistinguishable. No requirement of other factors was apparent. Deletion of C3bINA and beta 1H from the complet...
