SPC demonstrated threefold
enhancement using Pt–GO–

Eosin B
Cobalt-iron oxide powder
(300 mg/250 mL)
Ultrasonic bath (500 W)

Degradation was 78, 82, 83
and 87% under microwave,
photocatalysis, sonocatalysis and SPC, respectively.
Only minor improvement
reported

Negative effect was observed
for SPC (synergy index
was 0.7). Better synergy
of 1.6 was observed with
Fe
3+
-mediated SPC

Methyl Orange
CuO-TiO
2 /rGO (graphene
oxide) (1 mg/mL)
Ultrasonic bath (40 kHz)
UV light irradiation
Degradation of 99% in
90 min. Synergy factor of
3.7. 1.5% Cu and 2% GO
was optimum loading.
Photocatalyst reused more
than 5 times

96% degradation achieved
with SPC process. Degradation dominant in acidic
medium. Synergistic
removal as compared to
sonolysis and photolysis.
Doping enhances SPC
extent of degradation
