Large-scale liquid scintillation detectors are capable of providing spectral yields of the low energy solar neutrinos. These detectors require > 100 tons of liquid scintillator with high optical and radiopurity. In this paper requirements for low-energy neutrino detection by liquid scintillation are specified and the procedures to achieve low backgrounds in large-scale liquid scintillation detectors for solar neutrinos are reviewed. The design, operation and achievements of the purification of liquid scintillator in the Borexino solar neutrino detector are summarized. On-line purification has permitted the successful measurement of pp, 7Be and CNO low-energy solar neutrino fluxes.
