COMPOSITION AND METHOD FOR REMOVING ATOMIC SULFUR FROM AQUEOUS HETEROGEN DISPERSE SYSTEMS

A prepn. suitable for the removal of eleemental S from heterogeneous aq. dispn. systems contains: 1-40 vol.% of a mixt. of active agents and 60-99 vol.% of deionised or distd. H2O. These vol.% refer to the total vol. of the prepn. The prepn. contains (all vol.%-s): 60-90 mixt. of emulsifying agents 2-20 of at least a single component satisfying general formula (1): - where - R1: a 6-22C alkyl gp. X: a monovalent metal ion and 50-90 of a hydrocarbon fraction. The compsn. of the emulsifying agent mixt. relatees to the total wt. of the mixt. of active agents and also includes: (a) 1-10 of an ethoxylated fatty alcohol of general formula (2): R2-O-(C2H4O)n H (2) - where -: n = 2-6 R2 = 6-22C alkyl gp. and (b) 1-10 of at least one emulsifying agent of general formula (3), i.e. an alkali-, or amine-, or alkanol-amine salt of a di:carboxylic acid-(ethoxy-fatty alcohol)-half-ester: - where - n = 2-6 R2 = 6-22C alkyl gp. Y = alkali metal, amino gp.
