You'll find specifications of minimum series resistor to isolate capacitive loads in many OP datasheets.
In addition, the OP won't be able to drive larger output voltage magnitudes into a 1 uF capacitor. If you intend to handle larger signal frequencies than 40 Hz with non negligible level, you need to increase the filter impedance by several orders of magnitude (smaller capacitor, larger resistor). It may be reasonable to place a buffer amplifier behind the filter.
