The short answer
Disperse and disburse sound similar and both start with dis, but they describe unrelated actions. Disperse means to scatter, spread out, or break up, as when a crowd disperses after an event. Disburse means to pay out money, usually from a fund or account, as when a bank disburses a loan. The related noun forms are dispersal or dispersion for disperse, and disbursement for disburse. The word dispersement is a common blend of the two and is not standard English.
What each word means
Disperse applies to people, objects, gases, or information spreading outward from a central point. Police asked the crowd to disperse after the concert ended, and seeds disperse across a field when the wind carries them. The word can describe anything moving from concentrated to spread out, whether physical or figurative, such as rumors that disperse quickly through an office.
Disburse applies specifically to money leaving an account to be paid to someone. A university might disburse financial aid at the start of each semester, or a company might disburse employee bonuses in December. Disburse always involves a transaction: funds moving from one party to another, tracked and often documented.

Why 'dispersement' keeps appearing
Dispersement shows up often in casual and even some business writing because it blends the sound of disperse with the -ment ending of disbursement. Since both source words share the dis- prefix and a similar rhythm, writers reach for a word that feels familiar rather than checking which root applies. Style guides and dictionaries do not recognize dispersement as standard, so formal or financial writing should always use disbursement instead.
A quick usage note
If money changes hands, reach for disburse or disbursement. If people, objects, or gases are spreading out, reach for disperse or dispersal. A quick substitution test helps: try replacing the word with pay out. If pay out fits the sentence, disburse is correct; if it does not fit, disperse is almost certainly the word you need.
Remember it
Connect disburse to purse, since both involve money leaving a container to be handed out. Connect disperse to spread, since both describe things moving apart in different directions. With those two mental links, dispersement should never make it into your writing again, since neither root word supports that spelling.
