10. A method for ameliorating spent solids formation in a hydrogen sulfide scavenging system, the method comprising: scavenging hydrogen sulfide in a hydrogen sulfide scavenging composition that is:
(A) a triazine according to Formula I:

OG Complex Work Unit Chemistry
defined as a mixed triazine where R1, R2 and R3 are each independently selected from alkyl, ether, alkaryl or alkylhydroxy radicals and where R1, R2 and R3 are not all the same; or
(B) a mixture of two or more different compounds selected from the group consisting of:
(i) a triazine according to the formula I and defined as a pure triazine where R1, R2 and R3 are all the same and are alkyl, ether, alkaryl or alkylhydroxy radicals;
(ii) a mixed triazine; and
(iii) a bisoxozolidine.
