AB  - In this work, a novel alkali lignin-based adsorption material, alkali 
      lignin-based poly(tetraethylene pentamine-pyrogallol) (AL-PTAP), was prepared 
      using a Mannich reaction and catechol-amine reaction for removal of Cr(vi). It 
      was characterized by thermogravimetric analysis (TGA), scanning electron 
      microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and X-ray 
      photoelectron spectroscopy (XPS). The effects of tetraethylene pentamine (TEPA) 
      dosage, pyrogallol (PL) dosage, contact time, pH, temperature and other factors 
      on the adsorption behavior of the adsorbent were systematically investigated. 
      These experimental data show that the adsorption behavior conforms to the 
      pseudo-second-order kinetic model and the Langmuir isotherm model. The maximum 
      adsorption capacity is 769.2 mg g(-1) at 303 K, which is much higher than that of 
      alkali lignin (AL). AL-PTAP can achieve a removal rate of almost 100% for Cr(vi) 
      solutions with a concentration of less than 90 mg L(-1) at 1 min. Furthermore, 
      the toxic Cr(vi) is partly reduced to nontoxic Cr(iii) during the adsorption 
      process. Therefore, AL-PTAP is a fast and efficient alkali lignin-based 
      adsorbent, which is expected to improve the utilization value of alkali lignin in 
      Cr(vi) wastewater treatment.
