Four new materials,such as carbon suspension,sodium sulfonate of polyoxyethylene allyl glycidyl nonyl phenyl ether,vanillyl alcohol,vanillin,etc,in lead-acid storage batteries were reviewed.
It was shown that the energy of interaction between the polyoxyethylene and the noncrystalline SiO2 surface was below than hexadecyl accumbent benzene sulfonate.
Technologies for sulfonation including using sulfur trioxide as sulfonating agent and baking process and the sulfonation equipment such as tubular sulfonator as well are briefed.
A process for decolourization of anionic dye containing wastewater by using waste plastics in the presence of cationic auxiliary and sodium dodecylbenzene sulfonate has been studied.
